To find the rate (r), we can rearrange the formula:
r = d/t
Substituting the values given:
r = 212.5 miles / 2.5 hours
r = 85 mph
Therefore, you would need to travel at a rate of 85 mph to cover 212.5 miles in 2.5 hours.

To find the rate at which you must travel to cover 212.5 miles in 2.5 hours, you can use the formula r = d / t.
First, substitute the values into the formula:
r = 212.5 miles / 2.5 hours
Next, divide 212.5 miles by 2.5 hours:
r = 85 mph
Therefore, you must travel at a rate of 85 mph to cover 212.5 miles in 2.5 hours.
To find the rate at which you must travel to cover a certain distance in a given time, you can use the formula r = d / t, where r is the rate, d is the distance, and t is the time.
In this case, the distance is 212.5 miles and the time is 2.5 hours. You can plug these values into the formula:
r = 212.5 miles / 2.5 hours
Simplifying this calculation, you divide the distance by the time:
r = 85 miles per hour
So, the rate at which you must travel to cover 212.5 miles in 2.5 hours is 85 mph.
