Car and cyclist

Cyclist started from town at speed 18 km/h. After 1 hour 30 min started the car from town and caught up with the cyclist in 50 minutes. How fast was a car?

Result

v =  50.4 km/h

Solution:


18*(1+30/60+50/60)=v*50/60

50v = 2520

v = 2525 = 50.4

Calculated by our simple equation calculator.
