x-10 minutes is 10 minutes early, x-5 is 5 minutes early
at 60 mph, he travels 1 mile a minute, and in x-10 minutes will travel x-10 miles
at 45 mph, he travels 3/4 a mile a minute, and in x-5 minutes will travel (3/4)(x-5) or (3/4)x-3.75
those two are equal since the starting and ending points are the same.
