A and B set out from a and B at the same time and walk towards each other. A walks 5km per hour and B walks 3km per hour. If they meet at 2km from the midpoint of a and B, the distance between a and B is () km

sixteen
Meeting time: (2 + 2) / (5-3) = 2 hours
A. B distance between two places: (5 + 3) * 2 = 16km

Two circles are equal to a triangle and a square, a circle and a square are equal to a triangle, and a circle and a triangle are equal to (&# 160; &# 160;) squares

Circle = positive angle
Circle positive = angle
