Time and Distance word problems are common in Class 10 Maths and often appear in CBSE exams. Solving these problems efficiently requires understanding core concepts and applying short tricks to minimize time in competitive and board exams. In this guide, you’ll learn the fastest ways to solve such problems, especially useful for topics like trains, boats and streams, and relative speed. We also include solved examples, formulas, and smart approaches to build your accuracy and speed.
For Class 10 students preparing for boards or even exams like Olympiads and NTSE, mastering time, speed and distance formulas is crucial. This article explains the key tricks, embeds a detailed YouTube video, and connects you to related study resources like Chapterwise Maths Formulas and Sample Papers with Solutions.

What are Time and Distance Word Problems?
Time and Distance word problems test a student's ability to relate three main variables: Speed, Time, and Distance. These problems can be presented in various formats—basic direct proportion problems, those involving relative speeds, or compound scenarios like trains, boats, or pedestrians. Each type tests understanding of core concepts and application of formulas.
In most cases, students are required to find one of the three variables given the other two. For example, if a car travels 120 km in 2 hours, its speed is 60 km/h. These problems can increase in complexity when you add real-life twists like delays, overtaking, or motion in opposite directions.
To solve them effectively, students should revise all related formulas and regularly practice both textbook and additional resources. For a structured revision, refer to this NCERT Exemplar Guide for additional word problem practice.
When Do Time and Distance Questions Appear?
Time and Distance problems are typically featured in Chapter 2: Linear Equations or as a part of application-based questions in Arithmetic or Algebra. In the CBSE Class 10 board exam, you can expect at least 1 to 2 such questions, especially in the form of case studies or 3-mark problem-solving formats.
They’re also frequent in pre-board, sample, and Olympiad exams. If you’re using standard resources like RD Sharma, you’ll notice a dedicated section on these problems. For additional practice, you might refer to RD Sharma Class 10 Exercise 2.1 Solutions.
Understanding the type of questions and their placement helps in strategic preparation. For example, CBSE 2025 paper pattern emphasizes competency-based questions where such practical topics dominate.
Why Are These Questions Important?
Time and Distance problems hold weight not just in marks, but in real-world application. These are practical problems based on daily scenarios like commuting, racing, or logistics. Their logical framework also improves students' reasoning and analytical thinking—key skills tested in competitive exams such as JEE Foundation, NTSE, and even SSC later.
Mastering this topic also indirectly helps in understanding speed-time graphs and interpreting data, which is useful in higher grades. Moreover, when paired with good resources like Oswaal Question Banks or Book Comparison Guides, students can benchmark their understanding effectively.
Given their utility and recurring nature, students should not skip or postpone learning this topic. Building this early gives you confidence in similar logical reasoning questions in the future.
How to Solve Time and Distance Problems Easily?
Use the basic formula Speed = Distance / Time, and rearrange it depending on what is being asked. But to truly gain an edge, learn and apply short tricks:
- Equal Distance Shortcut: If two people cover the same distance at different speeds, use the formula: (2 × S1 × S2) / (S1 + S2) to find average speed.
- Train Problems: Time to cross a pole = Length of train / Speed. Time to cross a platform = (Length of train + platform) / Speed.
- Boats and Streams: Upstream speed = Speed of boat – speed of stream. Downstream = Boat + Stream.
Practicing these tricks will help reduce solving time. Explore more application-based problem-solving in this JEE Foundation Maths Guide.
Key Formulas for Time and Distance Questions
Here are some essential formulas you must remember:
- Speed = Distance / Time
- Time = Distance / Speed
- Distance = Speed × Time
- For relative speed: Add speeds if in opposite direction, subtract if in same direction
- Unit conversions: 1 km/hr = 5/18 m/s, 1 m/s = 18/5 km/hr

Solved Examples Using Short Tricks
Example 1: A train 180 m long is running at 60 km/h. How long will it take to pass a man standing on the platform?
Solution: Convert speed: 60 × 5/18 = 16.67 m/s. Time = 180 / 16.67 = 10.8 sec
Example 2: A car covers 200 km in 4 hours. What is its speed?
Solution: Speed = Distance / Time = 200 / 4 = 50 km/h

FAQs on Time and Distance Tricks
What is the basic formula for Time and Distance?
Speed = Distance / Time
How do I convert km/hr to m/s?
Multiply by 5/18
What kind of questions come in board exams?
Mostly trains, upstream/downstream, and average speed problems.
