Question

A water tank is being filled so that the height of the water

doubles every 10 seconds. Initially, there is 4 inches of
water in the tank.
Estimate the water height after 31 seconds.

Answer 1

There would be approximately 124 inches of water after 31 seconds

Explanation:

The reason it is 124 is because it starts off with 4 inches and it doubles every ten seconds so you would multiply 4 and 31 giving you the answer.
