Divide 720 by 6 to find how many miles he travels in one hour. That gives you his average mph.

Multiply his average mph by 8 to see how far he could drive in 8 hours.

Are you sure your numbers are correct. It's impossible to legally drive 720 miles in 6 hours.

I typed it wrong it should be 270 miles in 6 hours

Whew! That's better. If he had traveled 720 miles in 6 hours, his average speed would have been 120 mph.

Divide the miles by the number of hours.

270/6 = mph

mph x 8 = distance traveled in 8 hours.
