Question

a dolphin dove 31 meters below the surface. It traveled 16% of the total distance every second. What was the depth of the dolphin after 3 seconds?

Answer 1

The dolphin travelled a total of 31 meters.

Every second, the dolphin travelled 16% of 31 meters which is

`\begin{gathered} (16)/(100)*31\text{ meters } \\ =4.96\text{ meters} \end{gathered}`

After 3 seconds, the dolphin will travel

`\begin{gathered} 3*4.96 \\ =14.88\text{ meters} \end{gathered}`

Therefore, the answer is 14.88 meters
