Answer: 80 bottles per hour.
Step-by-step explanation:
It takes 45 seconds to fill up a single bottle, how many bottles does it fill up per hour.
We can say then that,
1 = 45
x = 3600
Cross multiplying we have,
45x = 3600
x= 3600/45
x = 80 bottles.
80 bottles is the approx capacity of the bottling line per hour.
