Quantitative Aptitude - Time and Distance - Formula & Concept Tutorial

1. Speed = Distance / Time
2. Time = Distance / Speed
3. Distance = Speed * Time
4. Average Speed = Total Distance / Total Time Taken
5. To convert km/hr to m/sec

x km/hr = ( x * 5/18) m/sec

6. To convert m/sec to km/hr

x m/sec = (x * 18/5) km/hr

7. If the ratio of the speed of A and B is a : b , then the ratio of the times taken by them to cover the same distance is
8. Suppose a man cover a certain distance at x km/hr and an equal distance at y km/hr. Then the average speed during the whole journey is .
9. When object are moving in the same direction with x and y speed, then relative speed will be x-y.
10. When object are moving in the opposite direction with x and y speed, then relative speed will be x+y
11.
