Answer: 3t = 60
Step-by-step explanation:
Answer:
The intensity of the first earthquake is 6.31 times the second one
Step-by-step explanation:
The given formulae is M=log(
)
Here for both the earthquakes the value of S is same.
Let the Intensity of the first earthquake be I1 and the second be I2.
Given M1=7.5
M2=6.7
Now M1=log(
)------1
M2=log(
)-----2
Now subtract 1 and 2 we get
M1-M2=log(
)
I1/I2=
I1=I2(
I1=I2*6.31

For company a it would be at the 8th hour and they would be 210 and for company b it would be at the 7th hour
40 students on each bus. 248 minus 8 equals 240. 240 divides by 6 equals 40.
