Step-by-step explanation:

In context to question asked,

We have to add 3 hours 42 minutes and 12 hours 12 minutes.​

As we know that,

When two or more units are used together then mathematical operations are only done on similar units.

So, we will add hour with hour and minutes with minutes.

Thus we will get it as,

$3\: hours \:42 \:minutes\:+12\: hours\: 12 \:minutes\\=> (3+12)\:Hours \: (42+12)\:minutes\\=>15\:Hours \:54\:minutes$

Answer 2

Answer:

Adding 3 hours 42 minutes and 12 hours 12 minutes we get 15:54

Step-by-step explanation:

We have to add 12 hours 12 minutes to 3 hours 42 minutes

An hour consists of 60 minutes, we will be adding hours first and then add minutes to it.

Adding 12 hours to 3:42 we get 15:42  in 24 hour clock

Adding 12 minutes to 15:42 we get 15:54

We can also write 15:54 as 3:54(am/pm) if the initial time is 3:42am then the final time will be 3:54pm and if initial time is 3:42pm then final time is 3:54am.
