Distance...4

Dawn left the hardware store and traveled toward her friend’s house at an average speed of 25 km/h. Nicole left some time later traveling in the same direction at the average speed of 30 km/h. After traveling for five hours Nicole caught up with Dawn. How long did Dawn travel before Nicole caught up?

Let me see.

Dawn:

D = 25(x + 5)

Nicole:

D = 30x

D = D

25(x + 5) = 30x

You say?
