It takes him 35 + 4 = 39 total minutes one way, so it would take him 39 x 2 = 78 minutes for 1 round trip.
convert 5 hours and 12 minutes into minutes: 1 hour = 60 minutes.
5 hours x 60 minutes = 300 minutes.
300 + 12 = 312 total minutes for the week.
Divide total minutes by minutes per round trip:

3x + 5 = 20
x = 5
