Question

the radius of a bus is 0.70 metre. how many revolution s will it make in covering 22 kilometres

Answer 1

Answer:

5002 revolutions

Step-by-step explanation:

first find how much distance the bus will travel in one revolution, which you can figure out by figuring out the circumference of the tyre.

2*pi*r

= 2*pi*0.70 metres

= 4.398......metres

divide this by 22,000m (22km = 22,000m)

This gives you how many revolutions the bus will make over the distance.

= 5002.012172
