4. At 3.3 x 10-8s
5. At 3.3 x 10-10s
6. At = 3 x 10-83
7. At = 3 x 10-9S
8. AL 3 x 10-10
9. At 3.3 x 10-6S
10. AR 3 x 10-7

Answer:

he correct answer is 7       3 10⁻⁹ s

Explanation:

The speed of light is constant, so we can use the uniform motion ratios

         v = x / t

         t = x / v

let's calculate

        t = 1 / 2.9972 10⁸8

       t = 3.336 10⁻⁹ s

the correct answer is 7       3 10⁻⁹ s
