please HELP.

answer:

0645 + 1135=1720

step-by-step explanation:

given : expression   0645 + 1135

to find : add the following military times?

solution :

we have given the expression in terms of a military time.

we have to convert the military time into 12-hour clock.

rule of conversion,

if the number of hours (two first digits) is between 0 and 12 the hour will be the same in both notations with the exception that 0 will be 12 a.m.(midnight) and 12 will be 12 p.m. (noon)

applying the conversion,

0645= 6 hours and 45 minutes.

1135 = 11 hours and 35 minutes.

adding the terms by hour to hour and minute to minute.

6 hour +11 hours = 16 hours

45 minutes + 35 minutes = 80 minutes

80 minutes = 1 hour and 20 minutes

i.e. total time taken is 17 hours and 20 minute.

convert back into military times,

17 hours and 20 minute = 1720.

therefore, 0645 + 1135=1720.
