b. After 3 hours
c. After 4 hours
d. After 5 hours

Answer 1

After 5 hours, Wolverine will have less than or equal to the amount of The Flash.

Step-by-step explanation:

To find out when Wolverine will have less than or equal to the amount of The Flash, we need to compare the rate at which they are filling or emptying their pools. The Flash is filling his 350-gallon pool at a rate of 35 gallons per hour, so after 1 hour, his pool will have 35 gallons of water. Wolverine is emptying his 200-gallon pool at a rate of 25 gallons per hour, so after 1 hour, his pool will have 175 gallons of water remaining.

To find the time when Wolverine will have less than or equal to the amount of The Flash, we can set up an equation: 200 - 25t ≤ 350 - 35t, where t is the number of hours. Simplifying this equation, we get 300 - 25t ≤ 350 - 35t. By solving this equation, we find that t ≥ 5. This means that after 5 hours, Wolverine will have less than or equal to the amount of The Flash.
