if a plane can travel 510 miles per hour with the wind and 410 miles per hour against the wind find the speed of the plane without the wind and the speed of the wind.
***
let x=speed of plane with no wind
let c=speed of the wind
x+c=speed of plane with the wind
x-c=speed of plane without the wind
distance=speed*travel time
..
(x+c)(1)=510
(x-c)(1)=410
add
2x=920
x=460
c=510-460=50
..
speed of plane with no wind=460mph
speed of the wind=50mph
