Cenda and Pepa

Cenda and Pepa went to the event. Cenda started alone. Canda started after him for 20 minutes. How long took Cenda to catch him? Cenda traveling at 15 km/h, and Pepa traveling at 25 km/h.

Result

t =  0.5 h

Solution:


15(t+20/60) = 25 t

600t = 300

t = 1/2 = 0.5

Calculated by our simple equation calculator.
