# Time Speed And Distance For IBPS RRB 2024 Exam, Check Important Questions with Solutions

Time, Speed, and Distance, a crucial topic in the quantitative aptitude section of the IBPS RRB exam. Mastering this topic can significantly enhance the candidate’s performance and help them score better. This article will provide a detailed explanation of the concepts, important formulas, and a set of practice questions with solutions to help a candidate prepare effectively for the IBPS RRB 2024 exam.

## Time Speed And Distance: Key Concept

01. Time, Speed, and Distance Relationship: The fundamental relationship between time, speed, and distance is given by the formula:

Distance = Speed x Time

From this, we can derive the other two equations:

• Speed = Distance / Time
• Time = Distance / Speed

02. Unit of Measurement

• Speed is usually measured in kilometres per hour (km/h) or meters per second (m/s).
• Distance is measured in kilometres (km) or meters (m).
• Time is measured in hours (h) or seconds (s).

Conversion Factors:

• 1 km/hr = 5/18 m/s
• 1 m/s = 18/5 km/hr

3. Average Speed: The average speed is calculated as the total distance travelled divided by the total time taken:
Average Speed = Total Distance / Total Time

4. Relative Speed

• When two objects are moving in the same direction, their relative speed is the difference between their speeds.
• When two objects are moving in opposite directions, their relative speed is the sum of their speeds.

## FAQs

### What is relative speed?

Relative speed is the speed of one object with respect to another. It is the sum of their speeds if they are moving in opposite directions and the difference if they are moving in the same direction.

### Why is practising time, speed, and distance questions important for the IBPS RRB exam?

Practising these questions is important because they are frequently asked in the quantitative aptitude section and can help you score better.
