let speed of wind be x mph
..
Distance traveled against wind =310
speed against wind = 165-x
Time taken = 310/165-x
..
Distance traveled with wind =350 miles.
speed with wind = x+165
time taken = 350/x+165
..
Both ways the time is same
310/165-x= 350/x+165
310(165-x)=350(165+x)
51150-310x = 57750+350x
660x=6600
x=10mph the speed of wind
