A car travels 32 miles for each gallon of gas.How many gallons of gas does it need to travel 192 miles
gladu [14]

Hi there! :)

<u>Answer:</u>

The car needs <u>6 gallons</u> of gas to travel 192 miles.


Step-by-step explanation:

In order to answer your question, you'll need to use the cross product method:

32 miles  → 1 gallon

192 miles → X gallons

<u>(1 × 192)</u> ÷ 32 = X gallons

<u>192 ÷ 32</u> = X gallons

<u>6</u> = X gallons


There you go! I really hope this helped, if there's anything just let me know! :)
