The distance the sea turtle swims in 3 seconds is 27 meters
How to find the distance the sea turtle can swim
Information from the double number line have that in 4 seconds the sea turtle swims 36 meters
We can find the speed in meters per seconds
= 36 / 4
= 9
So that in 3 seconds the sea turtle will cover
distance = 9 * 3
distance = 27 meters
