8 minutes 32 seconds +32 seconds + 37 minutes 18 seconds + 15 seconds
= (8 + 37) minutes + (32 + 32 + 18 + 15) seconds
= 45 minutes + 97 seconds
= 45 minutes + (60 + 37) seconds
= 45 minutes + (1 minutes 37 seconds)
= 46 minutes 37 seconds
= (8 + 37) minutes + (32 + 32 + 18 + 15) seconds
= 45 minutes + 97 seconds
= 45 minutes + (60 + 37) seconds
= 45 minutes + (1 minutes 37 seconds)
= 46 minutes 37 seconds
