In the formula RT equals D, are is right T is time and E is distance what is the rate for a runner who completes 7.5 miles in 1.5 hours (10 points)

A(11.25mph

B(9.0mph

C(6.0mph

D(5.0mph

well, since you want mi/hr, just divide the values, watching the units:

(7.5 mi)/(1.5 hr) = (7.5/1.5) mi/hr = 5.0 mi/hr

To find the rate of the runner, we can use the formula RT = D, where R is the rate, T is the time, and D is the distance. In this case, the runner completes 7.5 miles in 1.5 hours.

So, to find the rate, we need to divide the distance (D) by the time (T), which can be expressed as:

R = D / T

Plugging in the values, we have:

R = 7.5 miles / 1.5 hours

Simplifying the equation, we get:

R = 5 miles per hour

Therefore, the rate for the runner who completes 7.5 miles in 1.5 hours is 5.0 mph.

The correct answer is D(5.0mph).
