Question

After visiting the Titanic, Captain Brain and Mr. Pinky are taking the Alvin submarine back to the surface of the water. They start 2000 meters below the surface of the water, and ascend at 57 meters per hour.

Answer 1

35.09hours

Explanation:

Since we are not told what to find, we can as well look for the time it took to ascend

Given

Distance below surface of water = 2000m

Speed = 57m/hr

Required

Time

Using the formula;

Speed = Distance/Time

Time = Distance/Speed

Time = 2000/57

Time = 35.09hours

Hence it took 35.09hours to ascend
