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 [tex]\frac{1}{60} hr\\[/tex]

then mult. both sides by 75 we get the ratio

75 mi. to [tex]\frac{75}{60} hr\\[/tex]

simplifying we get

75 mi. to [tex]\frac{5}{4} hr[/tex]

or 1.25 hr.
