amistre64 · Answer

speed = distance/time.   since the distance stays the same, we can solve for the rest of it....somehow :)

o okay

amistre64 · Answer

As + Ws = 231
As - Ws = 173

As = 231 - Ws  and As = 173 + Ws

in other words:

231 - Ws = 173 + Ws

Solve for Ws....

amistre64 · Answer

231 - 173 = Ws + Ws

58 = 2Ws

58/2 = Ws

29 = Ws

The Wind speed should be 29 km/hour

amistre64 · Answer

As + 29 = 231

As = 231 - 29

Air speed = 202 km/hr


best double check me work tho :)
