Question

A dolphin dove 31 meters below the surface of the water to reach a fish. It traveled 16% of the total distance every second.

What was the depth of the dolphin after 3 seconds?

–19.84 meters

–4.96 meters

–7.44 meters

–14.88 meters

Answer 1

Total distance = 31 m
Traveled in a second = 16 * 31/100
                                  = 4.96 m

Traveled in 3 seconds = 14.88 m

So the answer is 14.88 m
