A turtle can walk 1/12 of a kilometer in an hour. The turtle is 1/5 of a kilometer away from a pond. At this speed, how long will it take the turtle to reach the pond? Khan academy
Since if the turtle reaches the pond the distance away is 0, we can make the equation \(\frac{1}{5}-\frac{1}{12}x=0\)
Solving we get 2.4 hours, or 144 minutes
