You can put this solution on YOUR website!
plane speed = 362 mph
wind speed = x mph
wind speed
speed against wind 362 - x
speed with wind 362 + x

Distance against wind 152 miles
Distance with wind 210 miles

t=d/r time against = time with wind
152/(362-x)=210 /(362+x)
152(362 +x)=210 (362-x)
55024+ 152x=76020-210x
210x+152x=20996
362x=20996
/ 362
x=58mph wind speed
