Question

Help please

Answer 1

440 with wind 340 without 25mph wind. I got this

speed = distance/time
time = distance/speed

for with wind(WW)

time = 440/speedWW

for without wind (WO)

time = 340/speedWO

we know the times the same so we can equate these

440/speedWW = 340/speedWO

using v as the actual speed of the airplane in still air

speedWW = v + 25mph

speed WO = v - 25mph

so we get 440/(v + 25) = 340/(v - 25)

solve that bad boy for v, and you have your damn answer
