Answer:
106 complete revolution
Step-by-step explanation:
distance s =50m = 5000cm
diameter= 15cm
radius r= 15/2 cm
circumference of wheel = 2πr = 2×22/7×15/2 = 22×15/7
circumference of wheel = 1 revolution
no.of revolutions = distance / circumference of wheel = 5000÷ (22×15/7) = 5000×7/22×15 = 106 complete revolution
