Question

The tires of a go-kart are 1 m in circumference. The tires revolve 15 times per second. What is the the distance the go-kart travels in 40 seconds?

Answer 1

600 m

Explanation:

The circumference of a tire is the distance around it. The distance around these tires is 1 m.

Since the tires revolve 15 times per second, this means every second the tires travel 15 m.

This means that in 40 seconds, the tires travel

15(40) = 600 m.

Answer 2

600m

Explanation:

For every revolution the go-kart tires make, the go-kart travels a distance equal to the circumference of its tires.

We can think about the relationship between distance and circumference like this: distance = circumference * number of revolutions

The tires revolve 15 times per second for 40 seconds.

15*40=600

Each tire revolves 600 times.

The circumference of the tires is 1 m, and the number of revolutions is 600.

1*600=600

In conclusion, The go-kart travels 600 m.
