Answer:

Hi

Step-by-step explanation:

2hrs 40 min 10 sec-1hr 20min 15sec

We want to convert all into seconds

2hrs 40 min 10sec,

2hrs=7200sec

40min=2400sec

10sec=10sec

1hr 20min 15sec,

1hr=3600sec

20min=1200sec

15sec=15sec

=7200sec 2400sec 10sec-3600sec 1200sec 15sec

=4795sec

Therefore,2hours 40minutes 10seconds-1hour 20minutes 15seconds=4795seconds.
