vagabundo [1.1K]

The time taken for the machine to fill 825 containers is 16.5 minutes.

<h3>What is time?</h3>

Time can be defined as the measurable period during which actions, processes, events, or conditions exist. The S.I unit of time is Seconds (s)

To calculate the time taken for the machine to fill 825 containers of oatmeal, we use the formula below.

Formula:

  • R = C/t.................. Equation 1

Where:

  • R = Number container filled by the machine in one minute.
  • C = Total number of containers
  • t = time taken the container

Make t the subject of the equation

  • t = C/R............... Equation 2

From the question,

Given:

  • C = 825 container of oatmeal
  • R = 50 containers of oatmeal per minute

Substitute the values above into equation 2

  • t = 825/50
  • t = 16.5 minutes.

Hence, the time taken for the machine to fill 825 containers is 16.5 minutes.
