2 × 2 Linear System Word Problem
need help with this 2 × 2 Linear System Word Problem. this is my nephew's homework and he asked my help. I don't know if my solution makes sense or if it's even correct.
Niki owns a small plane that has a speed if 80 km/h without any wind. in 90 minutes, Niki can fly from Virginia to her mansion on a secret island with the wind's help. coming back against the wind, it takes Niki 1 hour to cover half that distance. Find the rate of the wind in mph.
Here's my work. your help would be appreciated.
