If a P wave arrives at a seismic station at 9:07 AM and the S wave wave arrives at the same seismic station at 9:09 AM , About how far is that station from the Epicenter of the earthquake?

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
