Question

A race car driver lost 8 seconds off the leader for each of the 3 pit stops the driver made. At each of the next 2 pit stops the driver gained 10 seconds on the leader. Which represents the amount of time the driver is off the leader?

Answer 1

-4 seconds

Explanation:

The question says he lost 8 seconds off the leader for each of the 3 pit stops that he made

8 x 3 = 24

This means that 24 seconds was lost.

If 10 seconds were gained for the next 2 pit stops, the driver gained a total of

2 x 10 = 20seconds

The amount of time he is off leader =

20 -24

= -4 seconds

We have it that -4 seconds represents time he is off the leader.
