Question

the formula a= d/g gives the average gas milege a of a vehicle that uses g gallsons of gas to travel d miles. use the formula to find how many gallons of gas a vehicle with average gas mileage of 20.2 miles per gallon will use to travel 75 miles. round your answer to the nearest tenth.

Answer 1

a = d / g
a = 20.2
d = 75

20.2 = 75 / g ...multiply both sides by g, eliminating the g on the right side
20.2g = 75...divide both sides by 20.2, eliminating the 20.2 o the left side
g = 75 / 20.2
g = 3.71 rounds to 3.7 <==
