Question

Which unit rate is equivalent to 17 miles per gallon? (5 points)

Question 1 options:

1) 3 gallons
_________
51 miles




2) 51 miles
______
3 gallons



3) 34 miles
_____
4 gallons



4) 4 gallons
______
34 miles

Answer 1

The answer would be option 2) 51 miles/3 gallons.

Explanation:

First, every 17 miles needs 1 gallon. If you add 17 more miles, it'll be 34 miles and you'll need a 2nd gallon, so you can already eliminate options 3 and 4. If you add another 17 miles and a gallon, it'll give you 51 miles 3 gallons. Option 1 would not be the answer because if you did 3/51, you'll get a whole different answer in decimals. So the only other option to choose from is option 2.
