Flying with the wind a plane went 227 km/h. Flying into the same wind the plane only went 165 km/h. what is the speed of the wind?
How fast would the plane go if there would be no wind?

plane = 196

wind = 31

Step-by-step explanation:

This is a very nice question. It teaches you quite a bit about physics.

Let the plane's speed be p

Let the wind's speed be w

p + w = 227

p - w = 165          Add the two (you could also begin by subtracting)

2p =     392         Divide by 2

p =      392/2

p  =      196

p + w =  227

196 + w = 227

w = 227 - 196

w = 31
