Answer 1

Answer:

Step-by-step explanation:

The diameter (circumference) of the car wheel is 56 cm = 0.00056km  

i.e,. the car can cover 0.00056 km for one complete rotation of the wheel

Divide the required distance (17.6) with 0.00056  

This gives you the no.of rotations that a car wheel makes to complete that mentioned distance(17.6km),which is equal to 31428.571 (approximately 31428) rotations
