Juan is driving on a highway. he uses one gallon of gas every 30 miles he drives. the distance d (in miles) he drives on g gallons of gas. how far does Juan drive if he uses 5 gallons?

Answer: Juan drives 150 miles if he uses 5 gallons

Step-by-step explanation:

Juan is driving on a highway. he uses one gallon of gas every 30 miles he drives. This mean that his miles per gallon ratio is 1/30

If d represents the distance driven in miles and g represents the number of gallons,

d = g:1/30 = 30g

If 1 mile = 1/30 gallons

d miles would be 5 gallons

d = 5 / (1/30) = 150 miles
