Given:
A packing machine can pack 144 boxes of toothpaste in 24 minutes.
To find:
(i) How many boxes of toothpaste will be packed in 4 minutes?
(ii) What time will the machine take to pack 3600 boxes?
Solution:
First we have to find how many boxes does machine pack in 1 minute.
Since, 24 minutes is taken to pack 144 boxes.
Therefore, 1 minute is taken to pack ? boxes.
=> ? = 144/24
=> 6.
So, Machine packs 6 boxes in 1 minute.
Now, In 4 minutes the number of packed boxes will be 4×6 = 24 boxes.
And, In 1 minute number of packed boxes by machine is 6.
Therefore, In ? minute the number of packed boxes by machine is 3600.
=> ? = 3600/6 = 600minute.
We know that, 60minute = 1 hour.
Therefore, 600minute = 600/60 = 10 hour.
