Currently, the water level is 1/2 inch
Then, it increases 4 3/4 inches per hour.
How many hours if it reaches 33 3/4?
First, let's subtract it with 1/2 because we don't need to count the starting water level.
= 33 3/4 - 1/2
= 33 (3-2) / 4
= 33 1/4
Then divide 33 1/4 by 4 3/4
= 33 1/4 divided by 4 3/4
= 133/4 divided by 19/4
= 133 / 4 * 4/19
= 133 / 19
= 7
So the final answer is 7 hours.
