In the formula rt = d, r is the rate, t is time, and d is distance. What is the rate for a runner who completes 7.5 miles in 1.5 hours?
A) 11.25 mph
B) 9.0 mph

To find the rate for a runner who completes 7.5 miles in 1.5 hours, we can use the formula rt = d, where r is the rate, t is the time, and d is the distance.
The formula can be rearranged to solve for the rate (r), which gives us r = d / t.
In this case, the distance (d) is 7.5 miles and the time (t) is 1.5 hours.
Substituting these values into the formula, we get r = 7.5 miles / 1.5 hours = 5 miles/hour.
Therefore, the rate for the runner who completes 7.5 miles in 1.5 hours is 5.0 mph.
So, the correct answer is D) 5.0 mph.
r*T = d
r * 1.5 = 7.5
1.5r = 7.5
r =
