Question

A student skipped a step when she tried to convert 18 hours into seconds,

and she got the following incorrect result:
18 hours
60 seconds)
= 1080 seconds
1 minute
What conversion ratio did she skip in this multiple-step conversion?

Answer 1

The conversion of minutes to seconds is skipped in multiple-step conversion.

Explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours =
`18* 60 minutes`

=
`1080 minutes`.

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes =
`1080* 60 seconds`

=
`64800 seconds`.

Thus, 18 hours = 64800 seconds.

As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.
