Question

After a flood, the Garcia's had 5 inches of rain in their garage that was being pumped out at a rate of 0.5 inch per hour. The Peter's had 15 inches of rain in their garage being pumped out at a rate of 2.5 inches per hour. How many hours will it take for the water level of the Garcia's garage to be no less than the Peter's?

a) 10 hours
b) 5 hours
c) 15 hours
d) 7.5 hours

Answer 1

It will take at least 20 hours for the water level in the Garcia's garage to be no less than the Peter's.

Step-by-step explanation:

To find the number of hours it will take for the water level in the Garcia's garage to be no less than the Peter's, we need to set up an equation. The equation is: 5 + 0.5x >= 15, where x is the number of hours.

Let's solve the equation:

5 + 0.5x >= 15

Subtract 5 from both sides:

0.5x >= 10

Divide both sides by 0.5:

x >= 20

Therefore, it will take at least 20 hours for the water level in the Garcia's garage to be no less than the Peter's.
