Side-side-angle is not a congruence rule because a side cannot be in between an angle and a side. Angle-side-side is the same thing, a side cannot be in between an angle and a side.
Juan's time = x Yumi's time = x + 2 Yumi's distance = 3 miles Juan's distance = 2 miles Rate = distance/time Juan's rate = 2/x Yumi's rate = 3/(x + 2) The rates are equal so: 2/x = 3/(x + 2) 2x + 4 = 3x x = 4 hours Yumi's time = 4 + 2 = 6 hours The answer is D.
