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?

After 4 hours

Step-by-step explanation:

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

4h = 4 + 6h - 12

4h = 6h - 8

2h = 8

h = 4

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
