Two runners

Two runners ran simultaneously towards each other from locations distant 34.6 km. The average speed of the first runner was 1/5 higher than the average speed of the second runner.

How long should each ran a 34.6 km, if you know that they meet after 67 minutes?

Result

t₁ =  122.8 min
t₂ =  147.4 min
