Best ResponseYou've already chosen the best response.0from what is given in your question, we have the following two equations: \[\nu_{plane}\nu_{air}={1200 miles \over 3 hours}=400mph \rightarrow(1)\] \[v_{plane}+v_{air}={1200 miles \over 2 hours}=600mph\] solve the two equation to find both velocities

Best ResponseYou've already chosen the best response.0adding equation (1) and (2), we get: \[2\nu_{plane}=1000 mph \implies \nu_{plane}=500mph\] substitute in either equation (1) by v_plane=500, you get: \[500\nu_{air}=400mph \implies \nu_{air}=100mph\]
