9. Abu rides his bicycle for 5.00 x 102 meters in 10 seconds. What is the velocity in m/s and km/h?

10. A cat walks 18 km in 3 hours. What is the cat's average velocity in m/s?

11. Suppose a car travels at a constant 10 m/s. How far would it move in 1 hour? In 1
minute? In 1 second? In 1 millisecond?

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.
