Question

Gilbert is -17 meters under sea level every second(s) he gains 0.5 meters after how many seconds is he at sea level?

Answer 1

He is at sea level after 34 seconds

Explanation:

The height at sea level is given as 0 meters

So the change in height would be;

0- (-17) = 17 meters

There is a gain of 0.5 meters in 1 second

So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds
