Catching Up on Bicycle

Miles set off from point A at 13:00 at a speed of 4 km/h. At 3:30 PM, Lisa set off on her bicycle at 20 km/h in the same direction. How many minutes will it take Lisa to catch up with Miles?

Final Answer:

t =  37.5 min

Step-by-step explanation:


4·(15.5 - 13.00 + t/60) = 20·(t/60)

16t = 600


t = 600/16 = 37.5

t = 75/2 = 37.5
