Acertain car travels at a constant speed of 40 miles per hour. at this speed, the car can travel a distance of 25 miles for each gallon of fuel used. how many gallon sof fuel ar used when the car travels at this speed for 75 mins?

2 gallons

Step-by-step explanation:

At this speed, the car uses 1 gallon of fuel for a distance of 25 miles.

We need the number of miles the car travels in 75 minutes to find the amount of fuel it uses.

75 minutes * (1 hour)/(60 minutes) = 1.25 hours

speed = distance/time

distance = speed * time

distance = 40 miles/hour * 1.25 hours = 50 miles

In 75 minutes, at 40 mph, the car travels 50 miles.

(1 gal)/(25 miles) = x/(50 miles)

x = 2 gal

2 gallons

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
