Distance...2

[nycmathguy]

Lea left home and drove toward the ferry office at an average speed of 22 km.h. Trevon left at the same time and drove in the opposite direction with an average speed of 43 km/h. How long does Trevon need to drive before they are 65 km apart?

Let me see.

Lea:

rate = 22 kilometers/hour

time = x

Trevor:

rate = 45 kilometers/hour

time = x

Distance = 45 kilometers

22x + 45x = 65

Yes?

Wonderful. It feels good to be right.
