Question

Perform the indicated operation.Subtract 16 hours 36 minutes from 19 hours 12 minutes. ? hr ? min

Answer 1

Subtract

`16\text{hrs 36 mins}`

From

`19\text{hrs 12 minutes}`

Step 1: Subtract the minutes (note: we can't have negative minutes)

`12\min -36\min s=-24\min s`

Since we cannot have negative minutes (we will add 60 minutes to the negative minutes and then remove one hour

Substracting the hours, we will have

`\begin{gathered} 19-16=3hrs \\ to\text{ remove move one hour, we will have} \\ 3-1=2\text{hrs} \end{gathered}`

By adding 60 minutes to the negative minutes, we will have

`-24+60=36\min s`

Hence,

The final answer is 2 hours 36 mins
