Question

one light glow at every 13 secgap and first time blink 1pm 54 min 50 sec and last time blink 3pm 17 min 49 sec so how many time light bilnk this gap of time

Answer 1

Time between 1pm 54min 50 sec and 3pm 17min 50 sec is 6+60+17=83 min =4980sec
4980 sec -1 (because it is 17 min 49 sec)=4979sec
4979/13=383
Total times it rang=383+1 (because it also rang on 1pm 54min 50sec)
=384 times
