Question

Eric and Jan leave their house at one o-clock, following the same route. Jan walks at a steady pace of 4 mph. Eric walks at a leisurely 2 mph for 2 hours, and then jogs at 6 mph. When will he catch up with her?

Answer 1

After 4 hours

Explanation:

4h = 2(2) + 6(h - 2)

4h = 4 + 6h - 12

4h = 6h - 8

2h = 8

h = 4
