given :-
diameter of the wheel of the car = 77cm
it's circumference = πd
= 22/7 * 77
= 22 * 11
= 242cm = 2.42m
here we have to find the no. of revolutions of the wheel to cover 121km.
so first we needa convert 121km in meters.
121km = 12100m
∴ no. of revolutions it'll make = 12100/242
= 50
hence, the wheel of the car will make 50 revolutions to travel 121km.
