Juan jogs each day from his house to a local park, and then he jogs back along the same route. On his way to the park, he averages 4 miles per hour. On his way home, he averages 6 miles per hour. If the total trip takes 1 1/2 hours, which equation can be used to find x, the distance from Juan’s house to the park? x/4+x/6=1 x/4+x/6=1 1/2 4x6x=1 1/2 4x+6x=1
