PLEASE HELP!

John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. The trip took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is Johns grandmother's house?

Answer: 135 miles

Step-by-step explanation: If you go 70 miles in ones hour, then you’ll go 140 miles in 2 hours. Then it took 6 minutes longer because of traffic, and in traffic he drove 1 mile excluding 5 because he was 5 mph slower.
