Answers
Answer:
441
Step-by-step explanation:
Given The tremors of earthquake were felt at intervals of 15 seconds. The first tremor was felt at 08:54:57 and last tremor was felt at 10:45:12. How many times were the tremors felt?
We know that according to question tremors were felt at intervals of 15 secs. Now first tremor was felt at 8:54:57 and last was at 10:45:12. Now the difference between the two will be
10:45:12 – 8:54:57 = 9:104:72 – 8:54:57 = 1:50:15
Number of tremors felt will be = total time / 15
= 60 x 60 + 50 x 60 + 15 / 15
= 6615 / 15
= 441 times
one will be added in time intervals, so 441 + 1 = 442
Answer:
442
Step-by-step explanation:
The tremors of earthquake were felt at intervals of 15 seconds. Thefirst tremor was felt at 08:54:57 and last tremor was felt at 10:45:12
Total Time = 10: 45 : 12 - 8: 54 : 57
45 min 12 sec after 10 = 45 * 60 + 12 = 2712 sec
1 hr (9 - 10) = 3600 sec
5 min 3 sec before 9 = 5 * 60 + 3 = 303 sec
Total Time = 2712 + 3600 + 303 = 6615 sec
Total intervals of 15 secs in 6615 sec = 6615/15 = 441
As tremor was felt at 8: 54 : 57 & also at 10:45:12
so one will be added in time intervals
numbers of tremors felt = 441 +1 = 442
