plane flying with the wind travels 375 mi. in 3 hours. on the return trip flying against the wind the same plane takes 5 hours to travel 375 mi. find the rate of the plane in still air & the rate of the wind
define 2 variables
write 2 equations
Let the speed of plane be x miles per hour
Let the wind's speed be y miles per hour
x+y = 375/3 =125 miles per hour (speed of plane with the wind)
x-y =375/5 =75 miles per hour (speed of plane against the wind
y =125-100 =25
Answer : plane's speed =100 mile per hour
Wind's speed =25 mile sper hour
