Time and Distance Questions
FACTS AND FORMULAE FOR TIME AND DISTANCE
1.Speed = DistanceTime, Time=DistanceSpeed, Distance= (Speed×Time)
2. x km/hr = (x×518) m/sec
3. x m/sec = (x×185) km/hr
4. If the ratio of the speeds of A and B is a:b , then the ratio of the times taken by them to cover the same distance is or b : a
5. Suppose a man covers a certain distance at x km/ hr and an equal distance at y km/hr . Then, the average speed during the whole journey is 2xyx+ykm/hr.
