Answer: To cover 5.280 km distance, the wheel will take 20 minutes
Step-by-step explanation:
Diameter of a wheel, d= 3 m
Radius of the wheel, r= d/2= 3/2 = 1.5 m
The distance covered by the wheel in one revolution= 2*pi*r= 2*22/7*1.5
= 66/7 m
The distance covered by the wheel in one minute= 28*66/7= 264 m
5.280 km= 5.280*1000=5280 m
Time taken to cover 5.280 km= 5280/264= 20 min
Time taken to cover 5.280 km= 20 min
