Answer 2

The elapsed time in hours and minutes is calculated below:

Elapsed time is nothing but the time interval between two times.

(i) Initial time = 0815 hours.

Final time = 1945 hours.

So, elapsed time = (1945 - 0815) hours = 1130 hours

This is equivalent to 11 hours 30 minutes.

(ii) The time format is converted to 24 hour format for simplicity of calculations.

Initial = 1000 hours

Final = 1640 hours.

Elapsed = (1640 - 1000) hours = 0640 hours

This is equivalent to 6 hours 40 minutes.

(iii) Elapsed = (2302 - 1205) hours = 1057 hours

This is equivalent to 10 hours 57 minutes.

(iv) Time formats are converted to 24 hours.

Elapsed = (1315 - 0200) hours = 1115 hours

This is equivalent to 11 hours 15 minutes.
