What is the unit rate for 240 yards per 60 seconds

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.

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
