Explanation:

__________________________________________

Start at:

____________________

6:00 a.m.

____________________

Add 1 1/4 hours ; which is

1 + (1/4) hours:

Note: " 1 hr = 60 min." .

_____________________

So:

(1/4 hr) * (
`(60 min )/( 1 h)`) ;

= (1/4) * 60 min;

= (60/4) min.

= 15 min.

______________________

So: 1 1/4 hr = 1 hr. 15 min.;

______________________

So: Start at: 6:00 a.m .

Add " 1 1/4 hrs." ; i.e. add 1 hr 15 min.

_______________________

6:00 a.m + 1 hr = 7:00 a.m. ;

7:00 a.m. + 15 min. = 7: 15 a.m. ;

_______________________

Now, we are at:

_______________________

7:15 a.m. ;

Now add: "1/2 hour" to "7:15 a.m." to this time.

Note: " 1 hr = 60 min.

So;

"1/2 hr = (1/2) * (60 min) = (60 / 2) min. = 30 min.

________________________

So: we have 7:15 a.m. ;

we add "30 min." to this time.

and we have: 7:45 a.m.

The answer is: " 7:45 a.m. " .
