Time and Distance

Exercise:: Time and Distance-General Questions

1. Speed, Time and Distance
Speed = Distance/Time, Time = Distance/Speed, Distance = (Speed x Time)

2. km/h to m/s Conversion:
a km/hr = (a x 5/18)m/s

3. m/s to km/h Conversion
a m/s =(a x 18/5)km/hr

4. If the ratio of the speeds of A and B is a : b, then the ratio of the time taken by them to cover the same distance is 1/a : 1/b or b : a
5. Suppose a man covers a certain distance at x km/h and an equal distance at y km/h. Then, the average speed during the whole journey is (2xy / (x +y)) km/h.
