Question

Beth leaves her home on her bike, traveling down a long country road, at
the rate of 8 mph. Her brother, Brandon, left 15 minutes after Beth on his
golf cart along the same country road, traveling 12 mph. How long will it
take Brandon to catch up with Beth?

Beth has a 15 min head start at 8 mph , so 2 miles ahead

Brandon catches up at 4 mph (12 - 8)
... so it takes him 30 min to catch up
