Atrain travels 16 miles in 20 minutes at this rate , how many minutes will it take to trace 12 miles?

15 minutes

Step-by-step explanation:

You must find the unit rate.

You can find this by dividing 16 miles by 20 minutes

This formula would find how many per minute

The answer would be .64 miles per minutes.

Then Multiply .64 by 12 which would give you the answer of 7.68

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
