You can put this solution on YOUR website! A biker travels from his house at an average speed of 30 kilometers per hour. He gets a flat tire and walks home, using the same route, at an average of 10 kilometers per hour. If it took him a total of 40 minutes for the entire trip, then how far did the cyclist travel from his house before he got a flat tire?
--------------
Avg speed for the round trip = 2*30*10/(30+10) = 600/40 = 15 km/hr
--------------
15 km/hr * (2/3) hour = 10 km RT
= 5 km each way
