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?
if d = rt, then r = d/t
so plug in your numbers ...
r=d/t-->7.5mi/1.5hr=5mi/hr
To determine the rate, we can rearrange the formula rt=d to solve for r (rate). In this case, the distance (d) is 7.5 miles and the time (t) is 1.5 hours.
To solve for r, divide the distance by the time.
r = d / t
Substituting the given values:
r = 7.5 miles / 1.5 hours
Simplifying:
r = 5 miles/hour
Therefore, the rate for the runner who completes 7.5 miles in 1.5 hours is 5 miles per hour.
To find the rate of a runner who completes 7.5 miles in 1.5 hours, you can use the formula rt = d. In this case, the distance (d) is 7.5 miles and the time (t) is 1.5 hours. You want to find the rate (r).
To find the rate, you can rearrange the formula as r = d / t. Divide the distance (7.5 miles) by the time (1.5 hours):
r = 7.5 miles / 1.5 hours
Simplifying this division gives:
r = 5 miles per hour
So, the rate of the runner is 5 miles per hour.
