Given radius of wheel = 70 cm
Perimeter = 2πr=140π cm
Speed of car = 66 km/he = 66×

m/s
We know speed =
time
distance
Distance travelled in 10 min
66×

=
10×60
distance
distance = 66×

×10×60
distance = 11000 m=11 km$$
now 1 complete revolution = 2πr
Total no. of complete revolution =
140×

11,000
×100
=
140×22
1100000
×7=2500
Hence 2500 revolution complete by each Tyre in 10 m
