The speed would have to be greater than 0.08 mi/min
Work Step by Step
We know distance = speed*time To be at the park at 25 max, the equation is distance/speed\leq25. Since the distance is 2 miles, we can make an equation 2/25\leqspeed. This equals 0.08\leqspeed. So he has to run at a speed of 0.08 miles/min or faster.
