Question

A machine can make a box in 1 3/10 seconds. How many boxes can the machine make in 1 hour

Answer 1

Answer:

2,769 boxes in 1 hour.

Step-by-step explanation:

The time taken by a machine to make a box = $1\frac{3}{10}$ seconds = 1.3 seconds

We have to calculate how many boxes can the machine make in 1 hour.

As we know 60 seconds = 1 minute and 60 minute = 1 hour

∵  1.3 seconds taken by the machine to make = 1 box

∴ in one minute machine can make boxes = $\frac{60}{1.3}$

                                                                       = 46.15 boxes

∴ in 1 hour machine can make boxes = 46.15 × 60

                                                            = 2,769 boxes

Machine can make 2,769 boxes in 1 hour.

Answer 2

Since a machine make a box per 0.3 seconds, 1 hour would be 3600. 3600 divided by 0.3 is 12000. And that is the answer.
