Answer:

5 minutes

Step-by-step explanation:

let the time after which two lines will have filled an equal number of barrels is 'X' minutes.

so, according to the question after 'X' minutes;

⇒ number of barrels in old conveyer line = number of barrels in new conveyer line

⇒ 40x + 2X = 10X  

⇒ X = 5

How to create a pattern with the rule n 3?
SCORPION-xisa [38]
If you copied the "n 3" part, it's very likely that your job was to create a pattern with either the rule n^3 or n*3.

In the case of the former, we can start with the initial number of 1 and increase by 1.
In that way, using the rule n^3 would create this pattern of numbers: 1, 8, 27, 64, and so on. Or stated in another way 1*1*1, 2*2*2, 3*3*3, 4*4*4 ...

In the case of the latter, we can start with the initial number of 1 and increase it by 1. 
In this way, using the rule of n*3 would create this pattern of numbers: 3, 6, 9, 12, 15, 18 and o son. Or stated in another way 1*3, 2*3, 3*3, 4*3, 5*3 ...
