A Bird Flies 2/3 A Mile Per Minute, How Many Miles Does It Fly Per Hour?

This is a simple arithmetic question.
 
We have 60 minutes in 1 hour.
 
The bird flies 2/3 miles in 1 minute.
 
So for calculating how many miles it will fly in an hour, we do the following calculation.
 
2/3*60 = 40
 
Therefore, it will fly 40 miles in an hour!

I get 40 miles an hour.
