Conveyor belts A and B load x and y boxes a minute. Together they load 10 boxes a minute, and A in 3 minutes loads as many as B in 2 minutes. The two conditions are graphed. Read the rates from the graph.

Question

Accepted Answer

A: 4 boxes/min, B: 6 boxes/min. The lines x + y = 10 and 3x = 2y cross at (4, 6) : check 4 + 6 = 10 and 3 × 4 = 2 × 6 . So A loads 4 and B loads 6 boxes a minute.
