Drivers

Driver Franta and driver Karel are friends. They leave the start-stop both at the same time in the afternoon - at 13.30. When will they meet again if Franta goes around his route in 50 minutes and Karel in 40 minutes?

Result

t = 16:50 hh:mm Wrong answer

Solution:

50=252 40=235 LCM(50,40)=2352=200  x=LCM(50,40)=200  t=13.50+x/60=13.50+200/60=1016=16.83333=16:50 hh:mm



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
