Question 183982: An Airplane flies a roundtrip consisting of L miles each way. The average speed on the outward leg is 160 Miles per hour, and the average speed on the return leg is 240 miles per hour. Find the average speed for the entire trip.
I think that..
R=DT
160=100(T) so T=160/100
R=DT
240=100(T) so T=240/100...so, what now?
