Diameter of the wheels of a car = 80 cm
Circumference of wheels
=2πr=2r×π=80π cm
Distance = speed x time
Distance travelled by car in 10 minutes
=(66×1000×100×10)60=1100000 cm
No. of revolutions=Distance travelled by carCircumference of wheels
=110000080π=(1100000×7)(80×22)=4375
Hence, each wheel makes 4375 complete revolutions in 10 minutes.
