Answer:
It will take 11 robots to do the same job as the 15 humans
Explanation:
Given:
<em>Workers in use = 15</em>
<em>Each worker can move an average of 15 boxes per minute.</em>
<em>A robot has been built that can move an average of 21 boxes per minute</em>
15 worker would move:
15 * 15 boxes = 225 boxes per minute.
The number of robots it will take to move 225 boxes is:
225/21 = 10.7
It will take 11 robots to do the same job as the 15 humans
The train is going 140km per hour. 140 x 5.5 = 770, so it will take 5 and a half hours.
5x+2y=9
-3x-2y=-7
The +2y and -2y eliminate
2x=2
x=1
