The tremors of the earthquake were felt at intervals of 15 seconds. The first tremor was felt at 8:54:57 and the last tremor was felt at 10:45:12. How many times were the tremors felt?
Answer:
The tremors of the earthquake were felt at intervals of 15 seconds.
The first tremor was felt at 8:54:57 and the last tremor was felt at 10:45:12.
The first time =8:54:57 second time = 10:45:12.
The difference of the two time=1:50:15
so total time in seconds = (1 x 60 x 60) + (50 x 60) +15 = 6615 seconds
Since the tremors of earthquake were felt at intervals of 15 seconds
The number of times were the tremors felt =(6615/15) +2=441 + 2= 443 times
