Question 624670: Wilbur left the hardware store and traveled toward the recycling plant at an average speed of 33km/h. Mary left 2 hours later and traveled in the same direction but with an avg. spd. of 55km/h. How long did Wilbuer travel before Mary caught up?
When I solved this, I got the time that Wilbur traveled before Mary caught up to him. But I am not sure if the phrase "How long did Wilbuer travel before Mary caught up?" is asking for the distance or the time. Any answers?
