Which car can travel at the slowest rate? plz fast a) 300 miles in 4 hours b) 450 miles in 6 hours c) 750 miles in 10 hours d) 800 miles in 12 hours

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

As we can see, the first 3 rates are same, 75 mph, and the last one is mph. So clearly, the last rate is the slowest.

D is the right answer.
