A wheel makes 1000 revolutions in covering a distance of 88 km. the diameter of the wheel is?
Options:
A . 28 meters
B . 40 meters
C . 14 meters
D . 24 meters
Answer: Option A
Distance covered in one revolution = total distance travelled / total number of revolution. = ( 88 x 1000) / 1000 m = 88 mWe know that the distance covered in one revolution = circumference of the wheel.? ?d = 88? 22d / 7 = 88? d = 28 m
