A machine can seal 50 bottles of chilli sauce in a minute. Of the machine operates from 12:30 p.m. until 6:15 p.m, how many bottles of chilli sauce can be seale

Subject Arithmetic

There are 345 minutes, start from 12:30 p.m, until 6.15 p.m, hence we get
50 x 345 = 17250 bottles of chili sauce, which can be sealed during the period.

First, we should find out how long is the machine operated
t = t2 - t1
t = 18:15 - 12:30
t = 5:45
t = 5 hours and 45 minutes
t = 345 minutes
Then, we can find the amount of bottles sealed in the period of time.
x = t × bottles/minute
x = 345 minutes × 50 bottles/minute
x = 17,250 bottles

So, the machine sealed 17,250 bottles in that period of time.
