TIME AND DISTANCE - IMPORTANT FACTS AND FORMULA

VISHU GREETINGS

1.	Speed = [Distance/Time], Time=[Distance/Speed], Distance = (Speed*Time)
2.	x km/hr = [x*5/18] m/sec.
3.	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 1/a : 1/b or b:a.
4.	x m/sec = [x*18/5] km/hr.
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 [2xy/x+y] km/hr.
