Speed Time Distance Formula with Examples – Easy Maths Guide

Meta Description: Learn speed, time and distance formulas with easy examples, tricks, and practice questions. Best beginner maths guide for students.

Introduction

Speed, Time, and Distance is an important maths topic used in daily life and exams. It helps us calculate how fast something moves, how long it takes, and how far it travels.

In this lesson, you will learn this topic in a simple and easy way.

Basic Concept

There are three important terms:

• Speed: How fast an object moves
• Time: Duration of travel
• Distance: Total length covered

Important Formula

From this:

1. Speed = Distance / Time
2. Distance = Speed x Time
3. Time = Distance / Speed

Example 1

A car travels 60 km in 2 hours. Find speed.

We know that : D= 60 km , T= 2 hours

Speed = Distance / Time (apply formula)

= 60/ 2

Speed = 30 km/h

Example 2

A bike moves at 40 km/h for 3 hours. Find distance.

We know that : S= 40 km/h, T= 3 hours

Distance = Speed x Time

= 40 x 3

Distance = 120 km

Example 3

A train covers 150 km at 50 km/h. Find time.

we know that : D = 150 km , S= 50 km/h

Time = Distance / Speed

= 150 / 50

Time = 3 hours

Unit Conversion

• 1 km = 1000 m
• 1 hour = 60 minutes

Important conversion:

1. 1 km/h = 5/18 m/s
2. 1 m/s = 18/5 km/h

Shortcut Tips

• If distance increases, speed increases (for same time)
• If speed increases, time decreases (for same distance)
• Always use correct units

Real Life Examples

• Car and bike travel
• Train speed calculation
• Running and walking
• Delivery time estimation

Practice Questions

1. A car travels 100 km in 2 hours. Find speed.
2. A person walks at 5 km/h for 4 hours. Find distance.
3. A train covers 180 km at 60 km/h. Find time.
4. Convert 72 km/h into m/s.

Answers

1. 50 km/h
2. 20 km
3. 3 hours
4. 20 m/s

Common Mistakes

• Mixing units (km with meters)
• Using wrong formula
• Not converting time properly

Conclusion

Speed, Time, and Distance is easy when you understand the formulas and practice regularly. This topic is very important for exams and real-life calculations.
