Question

17. Ms. Harper drove her car 115 miles on 5
gallons of gasoline. At this rate, how many
miles can she travel on a full tank of 15
gallons?

Answer 1

Set it up as a proportion

115/5=n/15
And then you cross multiply
5•n=15•115
5n=1725
n=345 miles

Answer 2

Answer:

345

Step-by-step explanation:

5 goes into 15 3 times so 115 times 3 is 345
