A small kiddie pool starts with 110 gallons of water. The pool is being drained at a constant rate of 4
gallons per minute. How many minutes could have passed if the pool now has less than 74 gallons of
water left?

To determine how many minutes could have passed when the pool has less than 74 gallons of water left, we first need to find out how much water has drained. Starting with 110 gallons and wanting to find out when it drops below 74 gallons, we calculate:

110 - 74 = 36 gallons

This means 36 gallons must have been drained. Since the pool is draining at a rate of 4 gallons per minute, we can find the time taken to drain that amount:

36 gallons ÷ 4 gallons/minute = 9 minutes

So, less than 9 minutes could have passed for the pool to have less than 74 gallons of water left.
