Hi Sonu,
The diameter of the wheel is 88 cm so the circumference is
d = 88 = 276 cm which is 2.76 meters.
Thus in each revolution of the wheel the point travels 2.76 meters. The wheel makes 200 revolutions in a minute and there are 60 seconds in a minute so the wheel makes ^{200}/_{60} revolutions in one second.
What is the speed of the point in meters per second?
