Question

13
Mohan has a bicycle. It has
wheels.​

Answer 1

Answer:

Step-by-step explanation:

◾Race is of 1km

◾To convert km into m multiply the given value by 1000

1km = 1 x ( 1000)= 1000m

◾ Circumference of Mohan's bicycle =2.4 m

◾he had covered the distance 700m, then the tyre of Mohan's bicycle burst

Therefor,

◾The remaining Distance to finish the race = total distance - 700m

= 1000 - 700

= 300m

◾One round of wheel = circumference of circle = 2.4m

◾As we know the remaining distance to complete the race is 300m

Therefor

◾how many more times the wheel must go round = [remaining Distance to complete the race] / [circumference of the circle]

= 300 / 2.4

= 125 times

Answer 2

It is obvious that a bicycle will have wheels.

To reduce friction and force required to push bicycle.

hope it helps...
