Question

Ms. O'Malley's cousin lives 1,650 miles away. Ms. O'Malley won a gift card for 100 gallons of gas. If her car can travel 35 miles on each gallon, can she drive round trip to see her cousin on the free gas? Explain how you know.

Answer 1

I think so because if she/he has 100 gallons and she/he drives 35 miles than she would have to waist but still have some gas left to use

Answer 2

100 times 35=3500  
She can go 3500 miles on the free gas.  
She can go round trip to see her cousin on free gas because 1650+1650 is less than 3500
