Question

An airplane travels 6200 kilometers against the wind in 8 hours and 6840 kilometers with the wind in the same amount of time. What is the rate of the plane in
still air and what is the rate of the wind?​

Answer 1

Answer:

still air = 815, wind = 40

Step-by-step explanation:

x+y=against

x-y=with

8(x+y)=6200

8(x-y)=6840

Divide 8.

x-y=775

x+y=855

Subtract. 2 from 1

2y=80

y=40

x=815
