Question

Trey can drive his car 130 miles on 4 gallons of gas. At this rate how far can Trey drive on 6 gallons of gas?
Ms. Sue
130/4 = x/6

Cross multiply and solve for x.

Amy
32.2 miles

That's not the correct answer 32.2 miles
Ms. Sue
32.2 miles is not the right answer.

Obviously the correct answer is more than 130 miles.

Amy
195 miles is this correct
Ms. Sue
Yes. 195 miles is correct.

Amy
Ok thanks
Ms. Sue
You're welcome.
