A plane leaves the airport heading east at an airspeed of 250 miles per hour, then turns back and returns at an airspeed of 200 miles per hour. If the plane can stay in the air 9 hours, how far can it travel?
Cana nyone help me please?|||if the distance can be called d, then
d/250 + d/200 = 9 hours
0.004d + 0.005d = 9
d = 1000 miles
back check ... 1000/250 + 1000/200 = ? = 9|||That all depends on how far the plane flew before it turned around, how big a radius or turning circle it took to turn around, how high it climbed into the air and how far it has to come back down.
