Exercise 3

Nick and Kevin went to climb a mountain, starting from sea level. They didn't care for each other, but their girlfriends insisted they spend some time together so they could bond. However, they never promised they would go up the mountain at the same time. Sneaky. Nick started climbing at noon and was 500 feet up by 1 p.m. Kevin started climbing at 12:15 p.m., and at 12:30 p.m. was 75 feet up the mountain. When did Kevin pass Nick?
