MHB Solving Linear Equations: 2 Planes from LAX - Cbarker1

[cbarker1]

Dear Everyone,

I have some help setting up a system of linear equation. The problem states,
Two planes start from Los Angeles International Airport and fly in opposition directions. The second plane starts $\frac{1}{2}$ hour after the first plane, but its speed is 80 kilometers per hour faster. Find the airspeed of each plane if 2 hours after the first plane departs, the planes are 3200 kilometers apart.

I know the x is the first plane and y is the second plane.

Thank you

$\frac12$ what? What are the units?

after the first plane, but its speed is 80 kilometers per hour faster. Find the airspeed of each plane if 2 hours after the first plane departs, the planes are 3200 kilometers apart.
