Answer:
Hey mate!!!!!
First we should take out the circumference
Circumference = 2πr or πd
so assuming π as 22/7 we have
circumference =242 cm
Now since the circumference is in cm we should convert the distance also in cm.
Given distance 121km
1km = 1,00,000cm
121km = 1,21,00,000cm
Now to find out the revolution, we have to divide the distance by circumference
So distance=
50,000
So the wheel should complete 50,000 revolution.
Hope it helps dear friend ☺️✌️✌️
