A fire engine water tank holds 750 gallons of water. If the pump removes 250 gallons of water in 5 minutes, what is the change in the amount of water in gallons in 1 minute?

The fire engine pump removes 250 gallons in 5 minutes, therefore in 1 minute it removes 250/5 = <<250/5=50>>50 gallons of water.

Therefore, the change in the amount of water in 1 minute is 50 gallons. Answer: \boxed{50}.

To find the change in the amount of water in gallons in 1 minute, we can divide the amount of water removed in 5 minutes by 5.

Change in amount of water in 1 minute = 250 gallons / 5 minutes = 50 gallons

Therefore, the change in the amount of water in 1 minute is 50 gallons.

To find the change in the amount of water in 1 minute, we can divide the amount of water removed in 5 minutes by 5.

So, the change in the amount of water in 1 minute is 250 gallons / 5 minutes = 50 gallons/minute.
