Homework Help: ALGEBRA 1

A JET FLIES WITH THE WIND AT 1100km/hr and 750 km/hr against the same wind.
Find the rate of the wind and speed of the plane

PLEASE INCLUDE THE EQUATION OR SET FOR SOLUTION

Eq1: Vp + Vw = 1100.
Eq2: Vp - Vw = 750.
Add the Eqs:
2Vp = 1850
Vp = 925 km/h = Velocity of the plane.

In Eq1, substitute 925 for Vp:
925 + Vw = 1100
Vw = 1100 - 925 = 175 km/h = Velocity of the wind.
