Rachel’s unit walking rate in miles per hour and in hours per mile will be 2.125 and 0.47, respectively.
What is speed?
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Rachel enjoys exercising outdoors. Today she walked 5 2/3 miles in 2 2/3 hours.
The distance will be
D = 5 2/3
D = 17/3 miles
The time will be
T = 2 2/3
T = 8/3 hours
Then the speed of Rachel’s unit walking rate in miles per hour will be
S = (17/3) / (8/3)
S = 17 / 8
S = 2.125 miles per hour
And in hours per mile will be
⇒ 1/S
⇒ 1 / (17/8)
⇒ 8/17
⇒ 0.47 hours per mile
