You can put this solution on YOUR website!
Plane speed = 210 mph
wind speed given = x mph

speed against wind 210 - x
speed with wind 210 + x

Distance against wind 297 miles
Distance with wind 363 miles

t=d/r time against = time with wind -
297 / ( 210 - x )= 363 / ( 210 + x )
297 ( 210 + x )= 363 ( 210 -x )
62370 + 297 x = 76230 - -363 x
363 x 297 x 76230 + -62370
660 x = 13860
/ 660
x = 21 mph wind speed
