Final answer:
To run at least 1.5 miles at a pace of 3.75 mph, you will need to run for 0.4 hours, or 24 minutes.
Step-by-step explanation:
To calculate the time required to run at least 1.5 miles at a pace of 3.75 miles per hour (mph), we need to use the formula: time = distance ÷ speed. Here, the distance is 1.5 miles and the speed is 3.75 mph.
Substituting the given values into the formula gives us: time = 1.5 miles ÷ 3.75 mph.
Performing the division, we get: time = 0.4 hours.
Therefore, you would have to run for 0.4 hours, or 24 minutes, to cover a distance of at least 1.5 miles at a pace of 3.75 mph.
