Question

How many miles will light travel in one day if the speed of light is 300,000,000 meters per second.

(1.62 km = 1 mi)

Answer 1

`d=1.61* 10^(10)\ miles`

Explanation:

Given that,

The speed of light, v = 300,000,000

eWe need to find the distance light travel in 1 day. We know that,

1 day = 86400 seconds

Distance = speed × time

So,

`d=3* 10^8* 86400`

`d=2.592* 10^(13)\ m`

or

`d=0.001610* 10^(13)\\\\d=1.61* 10^(-3)* 10^(13)\\\\d=1.61* 10^(10)\ miles`

So, the required distance is equal to
`1.61* 10^(10)\ miles`.
