Using the formula r = d/t, where d is the distance in miles, r is the rate, and t is the time in hours, at which rate must you travel to cover 212.5 miles in 2.5 hours?
a- 71 mph
b- 106 mph
c- 150 mph
d- 85 mph ?
To calculate the rate at which you must travel to cover a certain distance in a certain time, you need to rearrange the formula to solve for r.
r = d / t
Given that d = 212.5 miles and t = 2.5 hours, you can substitute these values into the formula and solve for r.
r = 212.5 miles / 2.5 hours
r = 85 mph
Therefore, the correct answer is d- 85 mph.
To solve this problem, we can rearrange the formula r = d/t to solve for r.
First, plug in the given values:
d = 212.5 miles
t = 2.5 hours
Next, rearrange the formula:
r = d/t
r = 212.5 miles / 2.5 hours
r = 85 mph
Therefore, the correct option is d- 85 mph.
