Question

Solve. It takes an airplane 1 hour 30 minutes to fly 600 km againstthe wind. The return trip with the wind takes only 1 hour. Find thetotal flying time for the round trip if there was no wind. #6 camille can swim against the current at 1.5 m/s and with thecurrent at 3.5 m/s. Write an equation that expresses each fact. Howfast can she swim in still water? # 16 The 1080 km trip from Madrid to Pris takes 2 hours flyingagainst the wind and 1.5 hours flying with the wind. Find the speedof the plane in still air and the speed of the wind. Solve. It takes an airplane 1 hour 30 minutes to fly 600 km againstthe wind. The return trip with the wind takes only 1 hour.

Explanation / Answer

First find the velocity with the wind goes against 600/90=20/3 (km/min) Velocity with the wind goes for 600/60=10 (km/min) The average would be the real velocity of the plane (10+20/3)/2 = 50/6 (km/min) The time it takes to fly without the wind is t = s/v = 600 / (50/6) = 72 (min) which is 1h 12 min Hope this helps and please rate me as I took time to solve it,thank you
