How much time does it take light from a flash camera to reach a subject 6.0 meters across a room in scientific notation?

The time it takes light from a flash camera to reach a subject 6.0 meters across a room in scientific notation is 2.0 * 10^-8 s.

Explanation:

Given

t=?

d=6m

v=3*10^8 m/s

we have, v=d/t

here t=d/v

t=6m/3*10^8 m/s

v=2*10^-8 m/s

The time it takes light from a flash camera to reach a subject 6.0 meters across a room in scientific notation is 2.0 * 10^-8 s.
