Tim gets 28 miles per gallon of gas. how many gallons of gas would he use if he drove 55 mph for 2.75 hours

28 miles per gallon of gas. 

55 miles per hour * 2.75 hours = 151.25

Now, divide. 

151.25/28 = about 5 gallons. 

about 5 gallons of gas would be used. 

Lets look at the info we have:-

28 miles per gallon
55 mph
2.75 hrs

Lets solve:-

55 mile per hr
2.75 hr

55 × 2.75 = 151.25

151.25 ÷ 28 = 5.401 round to 5

So, in 2.75 hrs about 5 gallons of gas will be used.
