Acar uses 20 gallons of fuel to travel 440 miles. how much fuel will the car use to travel 1054 miles? the answer choices are about 40 gallons, about 48 gallons,about 231 gallons, about 440 gallons

You can solve this using an easy mathematical proportion:

you know that the car uses 20 gallons of fuel to travel 440 miles, so:

20 gallons : 440 miles = x : 1054 miles

The x is our unknown and stands for the fuel used to travel 1054 miles.

To solve it you should multiply the extreme knowns and then divide the result by the central known.

(20 gallons · 1054 miles) ÷ 440 miles

The unit miles cancel out so you're left with:

(21,080 gallons) ÷ 440 = 47.9 gallons ≈ 48 gallons

172 1/2 lb

Step-by-step explanation:

Determine the rate of change per month = lifts lifted in march - lift lifted in February

142 1/2 - 135 = 7 1/2

Determine the number of months from march to July = 4

increase in weight he would be able to carry in 4 months = 7.5 x 4 = 30 lb

weight he would be able to carry in april = 30 + 142 1/2 = 172 1/2
