1) Determine the unit rate of travel for each animal by dividing the distance traveled (y) by the number of hours (x).
Bottlenose Dolphin: 40 = 20 miles per hour
King Penguin: 40 = 5 miles per hour
Swordfish: 60 miles per hour

It takes the Dolphin 2 hours for swimming 40 miles. The penguin takes 8 hours and the swordfish will take 2/3 of an hour, which is 40 minutes to travel 40 miles.

Step-by-step explanation:

Given :

The bottlenose dolphin travels 40 miles in 2 hours. Or it takes 20 miles in 1 hour.

Now, dividing the distance by unit rate given in the question:

40/20=2 hours

40/5=8 hours

40÷60= 2/3 hour

Therefore,

- the dolphin takes 2 hours for swimming 40 miles.

- the penguin takes 8 hours

- the swordfish takes 2/3 rd of an hour

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
