Both of them make the same number of revolutions per second. If both of them meet after 10 seconds, the speed of the smaller wheel is (a) 22 cm/sec (b) 44 cm/sec (c) 66 cm/sec (d) 132 cm/sec

The persons start walking together and their steps measure 40 cm, 42 cm and 45 cm respectively. What is the minimum distance each should walk so that each can cover the same distance in complete steps?

The radius of a bicycle wheel is 14 cm . The distance covered by the wheel after making 50 complete rotation is
