Add the following:
7 hr 48 min 55 sec and 5 hr 35 min 32 sec

Given :

The given terms are 7 hr 48 min 55 sec and 5 hr 35 min 32 sec.

To do :

We have to add the given terms.

Solution :

We know that,

$1 hour = 60 minutes$ and $1 minute = 60 seconds$.

Therefore,

  hr  min  sec

  5    35     32

$+$7   48     55

---------------

12   83     87

----------------

$12  (60+23)   (60+27) = 12 hr (1hr+23min) (1min+27sec)$

                                       $= (12+1) hr (23+1) min 27 sec$

                                       $= 13 hr 24 min 27 sec$.

Therefore, the sum of 7 hr 48 min 55 sec and 5 hr 35 min 32 sec is 13 hr 24 min 27 sec.
