Taking a trip?




The Math Team in Addville traveled to Subtractville for a math competition. The bus averaged 40 mph from Addville to Subtractville but averaged 60 mph during the return trip. What was the average speed of the bus for the entire trip?


Thanks to the Elementary Brain Teaser

Good luck

Wouldn't it be 50 because

60+40=100%2=50

Is there some trick to it cause its a little late.
