Answer:
11 minutes and 25 seconds.
Explanation:
As we saw in the question above, the polishing rate of robot A is equal to the polishing rate of robot B. Furthermore, we saw that both can polish 88 pounds of gemstones in 6 minutes.
To find out how many minutes it would take A robot to polish 165 pounds of gemstones, we have to calculate as follows:
88 pounds of gemstones = 6 minutes.
165 pounds of gemstones = x minutes.
X = (165 * 6) / 88
X = 11.25
X = 11 minutes and 25 seconds.
