An airplane can travel at an airspeed of 300 km / h. If it travels 450 km going against the
wind in the same time that it can travel 630 km going with the wind, what is the speed of the
wind?

Answer 1

Step-by-step:

First, you do the unit rate of 300/450 which is 60/90 simplify until no more 20/30 then 4/6 finally the answer this part is 2/3.

Now, for the second part you will do 300/630 which is 100/210 until you get 10/21.
