If a street sweeper travels at 15 mph for 2.5 hours, how far does it travel?

To determine how far the street sweeper travels, you can use the formula for distance, which is distance = speed × time. In this scenario, the speed of the street sweeper is 15 miles per hour, and it travels for 2.5 hours.

By applying the formula:

Distance = Speed × Time
Distance = 15 miles per hour × 2.5 hours
Distance = 37.5 miles

This calculation shows that in 2.5 hours at a speed of 15 mph, the street sweeper would indeed cover a distance of 37.5 miles. This is why the correct answer is the one indicating 37.5 miles.
