Hey there!!
1 min - 60 seconds, as we have a value in seconds, first let us convert it into seconds
10 hours 39 minutes 24 seconds
24 seconds is already is seconds , so let us keep it aside
39 into seconds
as 1 min = 60 seconds
39 min = 60 × 39 seconds
= 2340 seconds
10 hours into seconds
1 hour = 60 min
60 min 60 × 60 seconds
= 3600 seconds
as it 10 hours ,
3600 × 10
= 36000 seconds
add them all up
36000 + 2340 + 24
total seconds = 38364 seconds
as 1 min = 60 seconds
we can write this as
60 seconds = 1 min
then
38364 seconds = ? min
38364 seconds = 38364 / 60 min
= 639.4 minutes
The required answer is 639.4
