To find the rate of the Adelie penguin, we have to divide the distance by time in the chart. 12/5 = 2.4 The speed of this penguin is 2.4 miles per hour. (It will be the same for all values in the table).
If we divide 3 miles by the speed of 2.4 mph, we get that it will take the penguin 1.25 hours to walk 3 miles.
