Dr. Tim recorded an unladen European swallow flapping it wings at a constant rate of 50 wing beats each 30 seconds how many times will the swallow beat its wings in 4 minutes

400 wing beats

Step-by-step explanation:

Find out the number of 30 second periods in 4 minutes.

If there are two 30 second periods in 1 minute, 4 minutes will have:

= 2 * 4

= 8

The swallow flaps its wings at 50 wing beats per 30 seconds. There are eight 30 seconds periods in 4 minutes .

= 50 * 8

= 400 wing beats

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
