Answer:
600 meters.
Explanation:
We have been given that the tires of a go-kart are 1 meter in circumference. The tires revolve 15 times per second.
We know that the distance traveled by a circular thing equals to circumference of circle.
To find the distance traveled by go-kart, we will multiply distance traveled by cart in one second by 40.

![\text{Distance}=\frac{\text{15 meter}}{\text{second}}* \text{40 seconds}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/5a4tuhdkap6qes6r8nrgpys17fk1b76hr1.png)
![\text{Distance}=\text{15 meter}* 40](https://img.qammunity.org/2019/formulas/mathematics/middle-school/3npcnvwetarmgw8p41jhokunwsc89ifoe7.png)
![\text{Distance}=600\text{ meter}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/b2flck6w1ym0irfwitea957zubueg9nxia.png)
Therefore, the go-cart traveled 600 meters in 40 seconds.
