Question

The first track on Sean's new CD has been playing for 55 seconds. This is 42 seconds less than the time of the entire first track. How long is the first track on this CD?

Answer 1

`97` seconds or `1` minute and `37` seconds

Explanation:

The first track has played for `55` seconds, but this number is `42` seconds less than the entire length of the track. The entire length is therefore `55+42`, or `97` seconds.

A minute is `60` seconds. `97-60=37 rarr 97` seconds is equivalent to `1` minute and `37` seconds.
