How many minutes are in 230 seconds

1 answer

To convert seconds into minutes using dimensional analysis, we will use the fact that:

1 minute = 60 seconds

We can set up the conversion as follows:

  1. Start with the given quantity in seconds:

\[ 230 , \text{seconds} \]

  1. Use the conversion factor to change seconds to minutes. To do this, we'll multiply by a fraction that represents the conversion. The fraction will have minutes in the numerator and seconds in the denominator:

\[ 230 , \text{seconds} \times \frac{1 , \text{minute}}{60 , \text{seconds}} \]

  1. Now we perform the multiplication:

\[ = \frac{230 , \text{minutes}}{60} \]

  1. Calculate the value:

\[ = \frac{230}{60} , \text{minutes} \]

Calculating \(230 \div 60\) gives:

\[ \approx 3.8333 , \text{minutes} \]

  1. We can round this to a more manageable number, if necessary:

\[ 3.83 , \text{minutes} \quad \text{(to two decimal places)} \]

Thus, \(230 , \text{seconds} \approx 3.83 , \text{minutes}\).

So the final answer is:

\[ \boxed{3.83 , \text{minutes}} \]
