A bird flies two thirds miles a minute how many mph is the flying?

To convert the bird's speed from miles per minute to miles per hour, we need to multiply its speed by 60 (since there are 60 minutes in an hour).

The bird flies two-thirds of a mile per minute, so its speed in miles per hour is:

```

(2/3) miles / minute * 60 minutes / hour = 40 miles / hour

```

Therefore, the bird is flying at a speed of 40 miles per hour.
