Question 432167: The Friendship Trail is a multi-use recreational trail that runs from Port Colborne to Fort Erie, an distance of 25 km. At 2 pm. Debbie starts rollerblading from Port Colborne at 10 km/h. At the same time, Ken starts bicycling from Fort Erie at 20 km/h. When will they meet each other? How far from Fort Erie will they be at this time?
Answer by jorel1380(3719)   (Show Source):
You can put this solution on YOUR website! If Debbie's going 10km/h, and Ken's going 20 km/h, then together they are traveling at 30 km/h.
25 km/30km/h=5/6 hour, or 50 minutes. Thus they will meet at 2:50 p.m..
If Ken is leaving Fort Erie at 20 km/h, after 5/6 hour he will have traveled
5/6X20 or l00/6 kilometers from Fort Erie when they meet.
