A student is recording how far an ant can crawl over time. He gets so interested in the project that he forgets to enter a few data points. Based on the data in the table the values for the missing data points are MOST LIKELY
A)
9 minutes and 8 inches
B)
9 minutes and 9 inches
10 minutes and 9 inches
D)
10 minutes and 10 inch
Eliminate

10 minutes and 9 inches

Explanation:

I got it right and they are counting by 2 and 3

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
