You may edit the question. Maybe convert formulae
speed with no wind=12 mph
wind speed =w
speed against wind =12-w mph
speed with wind=12+w mph
time=t
distance against wind =t(12-w)=8.......................1
distance with wind=t(w+12)=14...................2
eqn.2/eqn.1=(w+12)/(12-w)=14/8=7/4
4(w+12)=7(12-w)
4w+48=84-7w
7w+4w=84-48=36
11w=36
w=36/11=3.27 mph
