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 will take the Dolphin 2 hours to swim 40 miles. The penguin will take 8 hours. The swordfish will take 2/3 of an hour, that is 40 minutes, to travel 40 miles.

Step-by-step explanation: Divide the given distance by the unit rate given:

40/20=2 hours

40/5=8 hours

40÷60= 2/3 hour

This is the reverse of the process described in the question.

If the dolphin takes 2 hours to swim 40 miles, what is its unit rate? x ÷ y = R 40 miles÷2 hours= 20 mph.

40 miles ÷ 2/3 hour

3/2 × 40 = 60 mph

I hope this helps.
