A. 30 - 15 / 2 - 1 = 15 / 1 = 15 miles per hour

B. 60 - 15 / 4 - 1 = 45 / 3 = 15 miles per hour

C. 60 - 30 / 4 - 2 = 30 / 2 = 15 miles per hour

D. Yes, the graph is a line throughout the origin.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
