Question

James adds 12 minutes of music to his playlist. He adds 3 songs. The first song lasts 279 seconds. The second song lasts 215 seconds. How long is the third song?

Answer 1

226 seconds

Explanations:

The total minutes of songs James adds to his playlist is 12 minutes.

Convert 12minutes to seconds

`\begin{gathered} 12minutes=12*60seconds \\ 12minutes=720seconds \end{gathered}`

If he adds 3 songs and the first song and second song lasts 279 seconds and 215 seconds respectively, the amount of time the third song will last is expressed as:

`\begin{gathered} t_3=total\text{ time}-(279+215) \\ t_3=720-494 \\ t_3=226seconds \end{gathered}`

This shows that the third song will lasts 226 seconds
