Two swimming pools have 30 feet of water. The water level in Pool A is changing by -4 feet per hour. The water level in Pool B is changing by -5 feet per hour. After 5 hours, which pool will have a higher water level, and what is the difference in their water levels?

Pool A will have a higher water level by 4 feet.
Pool B will have a higher water level by 4 feet.
Pool A will have a higher water level by 5 feet.
Pool B will have a higher water level by 5 feet.
After 5 hours, the water level in Pool A will decrease by 4 feet per hour for a total of 4 * 5 = <<4*5=20>>20 feet.
After 5 hours, the water level in Pool B will decrease by 5 feet per hour for a total of 5 * 5 = <<5*5=25>>25 feet.
Since the initial water level was the same in both pools, Pool B will have a higher water level by 25 - 20 = <<25-20=5>>5 feet.
Therefore, Pool B will have a higher water level by 5 feet.
