I just applied the values:
r revolutions in 1 min, so 60r in 60mins.
Consider a point on this wheel. In each revolution of the larger wheel, this point travels 40 cms, so at the end of 60r it travels 2400cms.
How many revolutions will it take for a point on the smaller wheel to cover this distance? 2400/32 = 75r
