Asked by Cynthia

I don't have a close about this question !!!!!!!! It takes you 3 hours to drive to a concert 135 miles away. You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads. How many miles do you drive on highways? The rest of the road?

55 t + 40 (3-t) = 135


Answered by Damon
55 t +120 - 40 t = 135

15 t = 15

t = 1 hour at 55 so 55 miles on highway

2 hours at 40 = 80 miles on dirt
