using the formula r=d/t, where d is distance, r is the rate, and t is the time in hours. At which rate must you travel to cover 227.5 miles in 3.5 hours?
65 mph

95 mph
it is 65
A. 65
r=d/t
r= 227/3.5
227/3.5= 64.1
so at least 65 miles per hour.
using the formula r=d/t, where d is distance, r is the rate, and t is the time in hours. At which rate must you travel to cover 227.5 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, you need to find the rate at which you must travel to cover 227.5 miles in 3.5 hours.
Substituting the given values into the formula, we have:
r = 227.5 miles / 3.5 hours
Using a calculator, we can now divide 227.5 by 3.5:
r ≈ 65 mph
Therefore, the correct answer is 65 mph.
Thanks!
given d=227.5 miles and t=3.5 hours
to find r. simply substitute those values in r=d/t and the answer is 65mph
75mph
It's 337.5 divided by 4.5
