Final answer:
It would take 100 minutes to fill a 150-gallon tub when water runs at a rate of 1.5 gallons per minute. The calculation is simply the total gallon capacity (150) divided by the rate (1.5 gallons/min).
Step-by-step explanation:
To determine how long it would take to fill a tub with a 150-gallon capacity when water runs from a pump at a rate of 1.5 gallons per minute, we need to divide the total gallons of the tub by the rate at which the water is pumped. The calculation is as follows:
Time to fill = Total Capacity / Rate
Time to fill = 150 gallons / 1.5 gallons per minute = 100 minutes.
So, at this rate it would take 100 minutes to fill the tub. This is the correct answer which corresponds to option b.
