Hello,

Going against the wind, a domestic plane can travel 5/8 of the distance it can travel in one hour if it is going with the wind. If the plane can fly 300 kilometers an hour in calm air, what is the velocity of the wind?

Answer:- There are five answers given by the author to choose,

1)62.93kph.

2)96.23kph.

3) 63.92kph.

4)69.23kph.

5)Doubtful.

I think 62.93 kph is the correct answer. I computed it as follows:$300*\frac58=187.5, \frac{187.5}{300}=0.625$ So, 0.625*100=62.5 kph. But the author says it is wrong. Then what is the correct answer?

If any member knows the correct answer, he/she may reply to this multiple choice question.
