Answer:
=7142.86 or 7143 revolutions
Step-by-step explanation:
radius of wheel = 70 cm
circumference of the wheel=22/7*2*70
=1540 cm or 15.4 m
speed = 66 km/h
speed in m/s=66*5/18 = 330/18 m/s
time in seconds = 10*60 = 600
total distance = speed * time =600*330/18 = 110,000 m
total revolution = total dictance / circumference of wheel
=110,000/15.4
=7142.86 or 7143 revolutions
