Step-by-step explanation:

Shelly's first race time is 43.13 seconds.

Shelly's second race times is 43.1 seconds.

Basically, she improved 0.03 seconds, because 43.13 - 43.1 = 0.03.

If she keeps this patterns that means she will improve 0.03 each race.

So, the third race times is 43.1 - 0.03 = 43.07 seconds.

The fourth race time is 43.07 - 0.03 = 43.04 seconds.

Therefore, the time in the fourth race is 43.04 seconds, because she's improving at a constant rate of 0.03 seconds per race.
