Question 778498
A plane whose air speed is 150 mi/h flew from Abbot to Blair in two hours with a tail wind. On the return trip against the same wind, the plane was still 60 mi from Abbot after two hours. Find the wind speed and the distance between Abbot and Blair

let the wind speed be x

With wind, speed = 150+x

Time =2 hours
Distance = 2(150+x)

Return

speed = 150-x
time = 2 hours

Distance = 60 less

2(150+x)=2(150-x)+60

300+2x=300-2x+60

4x=60
/4
x=15 mph

distance = speed *t

d=(150+15)*2
=330 miles
