Your ear is capable of differentiating sounds that arrive at the ear just 1.00 ms apart. What is the minimum distance (in cm) between two speakers that produce sounds that arrive at noticeably different times on a day when the speed of sound is 343 m/s?

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
