[tex]\sf Explanation:[/tex]
Ratio Equation:
Let's use 'd' for the miles he'll drive in 11 hours.
d/715 = 11/13
13d = 11 × 715
13d = 7,865
d = 7,865/13
d = 605 miles
_____________________________
You could also divide the amount of miles by the number of hours to get miles per hour, and then multiply that by 11.
715 ÷ 13 = 55
55 × 11 = 605
