PLEASE ANSWER STEP BY STEP ​

Answer 1

Step-by-step explanation:

Given radius of wheel = 70 cm

Perimeter = 2πr=140π cm

Speed of car = 66 km/he = 66×

18

5

m/s

We know speed =

time

distance

Distance travelled in 10 min

66×

18

5

=

10×60

distance

distance = 66×

18

5

×10×60

distance = 11000 m=11 km$$

now 1 complete revolution = 2πr

Total no. of complete revolution =

140×

7

22

11,000

×100

=

140×22

1100000

×7=2500

Hence 2500 revolution complete by each Tyre in 10 m
