Answer:
First Time = 1 hour 54 mins 50 seconds
Last Time = 3 hours 17 mins 49 seconds
Duration = (3h 17min 49s) - (1h 54 min 50 s)
= 1 h 22 mins 59 s
= 4979 seconds
Number of 13 seconds interval = 4979 ÷ 13
= 383
Total number of times the light is seen = 383 + 1
= 384
Answer: The light was seen 384 times
