Answer 2

Answer:

680 sec (or) 11 min 20 sec

Step-by-step explanation:

1 min = 60 sec

15 min 5 sec = 15 × 60 + 5 sec

= 905 sec

3 min 45 sec = 3 × 60 + 45 sec

= 225 sec

905 sec - 225 sec = 680 sec

60 sec = 1 min

= 680 sec = 680 ÷ 60 = 11 min (quotient)

= 11 min × 60 sec = 660 sec

= 680 sec - 660 sec

= 11 min 20 sec
