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

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
