450/6=75

750/10=75

800/12=66.6666667

Answer 2

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: $rate=\frac{Distance}{Time}$

(A)

rate = $\frac{300}{4}=75$ mph (miles per hour)

(B)

rate = $\frac{450}{6}=75$ mph

(C)

rate = $\frac{750}{10}=75$ mph

(D)

rate = $\frac{800}{12}=66\frac{2}{3}$ mph

As we can see, the first 3 rates are same, 75 mph, and the last one is $66\frac{2}{3}$ mph. So clearly, the last rate is the slowest.

D is the right answer.
