Paul and Honza

Honza went to chat on a bike without a break 4.0 hours. Paul the same way without breaks 50 minutes longer. The difference between the speeds of the two boys was the one kilometer per hour. How fast was Paul, if you know that the speed of the boys did not change during the journey?

Result

p =  4.8 km/h

Solution:


4.0 h = p ( 4.0 + 50/60)
h = p+1

240h-290p = 0
h-p = 1

h = 295 = 5.8
p = 245 = 4.8

Do you have a linear equation or system of equations and looking for its solution? Or do you have quadratic equation? Do you want to convert length units?
