Young Cyclists

Charlie and Peter are going to the Young Cyclists' Meeting today. Peter is still unable to start, so Charlie goes first alone. Peter follows him for 20 minutes. How long does it take to reach Charlie? Charlie travels at an average speed of 15 km/h, and Peter's riding speed is 25 km/h.

Final Answer:

t =  0.5 h

Step-by-step explanation:


15(t+20/60) = 25t

15·(t+20/60) = 25·t

600t = 300


t = 300/600 = 0.5

t = 1/2 = 0.5
