Question

An automatic machine produces $1$ part every $2.3$ minutes.

How many parts are produced in $8$ hours if the machine runs constantly?

Answer 1

Explanation:

An automatic machine produces $1$ part every $2.3$ minutes.

$1$ hour is equal to $60$ minutes.

So, in $8$ hours there are

$8\times 60=480$ minutes.

Let $x$ be the number of parts the machine produce in $480$ minutes.

Divide $480$ by $2.3$ to find $x$.

$$\begin{gathered} \Rightarrow x=\frac{480}{2.3} \\ =208.70 \end{gathered}$$

But, number of parts is a whole number.

Therefore, the number of parts the machine produce in $480$ minutes is $208$.
