Question

How many revolutions does a go kart with a wheel circumference of 62.8318 inches make in a 1609 m race? Please answer as quickly as possible!

Answer 1

Answer: 1008 revolutions

Explanation:

1 revolution is equal to
`2\pi r`

To find how many revolutions the wheel makes, you must divide the distance traveled in the race between the circumference of the wheel

You must first convert 62.8318 in to meters.

We know that 1 inch is 0.0254 meters

Then

`62.8318\ in*(0.0254\ m)/(1\ in)= 1.5959\ m`

`revolutions = (1609)/(1.5959)\\\\revolutions=1008.21\\`

Finally The wheel made 1008.21 revolutions
