Answer:
D
Step-by-step explanation:
Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.
Note: 
(A)
rate = 
mph (miles per hour)
(B)
rate = 
mph
(C)
rate = 
mph
(D)
rate =

mph. So clearly, the last rate is the slowest.</u>
