Question

Wind is blowing west to east along twoparallelracs. Two trais moving with the same speed in opposite directions on these tracks have the steam tracks. If one stream track isdouble than the other, what is the speed of each train ?

Answer 1

Let (u) and (w) be the velocity of each train and wind respectively. As oer qyestuib, (v + v) =2 (v-w) or v=3= w.r.t., velocity of each train is ` 3 times the velocity of wind.
