The wording is confusing. WITH the wind, the plane goes faster; AGAINST the wind, the plane goes slower.

This tabulated data is arranged accordingly:

AGNST ______________r-10____________4.3____________d
WITH________________r+10____________3.9____________d

Distance equal each way, so form one equation with one variable.
