the no of seconds between 1:57:58 and 3:20:47 are 4969

4) They stayed there for 23 days.

please tell me it is correct.

explanation -> They enjoyed 13 days.

suppose they enjoyed all 11 mornings it means it would

have been raining for 11 afternoons.

and 2 more days they enjoyed,they can be 2 afternoons ,

on which raining can be in morning.

They enjoyed for more 10 afternoons.

So, total number of days they enjoyed=23.
