Question

Light travels about 180 million kilometers in 10 minutes. How far does it travel in one minute? How far does it travel in one second?

Answer 1

The light travels distance in 1 minute=18 million kilometers

The light travels distance in 1 second=0.3 million kilometers

Explanation:

We are given that

Light travels total distance in 10 minutes=180 million kilometers

We have to find the distance travels by light in 1 minute and in 1 seconds.

By unitary method

Distance travel by light in 1 min=
`(180)/(10)`million kilometers=18 million kilometers

Distance travel by light in 1 min=18 million kilometers

We know that 1 minute=60 seconds

In 60 seconds, light travels distance =18 million kilometers

In 1 second, light travels distance =
`(18)/(60)=0.3` million kilometers

Hence, the light travels distance in 1 minute=18 million kilometers

The light travels distance in 1 second=0.3 million kilometers

Answer 2

18 million kilometers in one min. and 0.3 million kilometers in one second

Explanation:

so the one min. is easy because all you have to do is take 180 and divide it by 10 and you get 18 million kilometers in one min. and then you would take 18 and divide it by 60 and you would get 0.3 million kilometers in one second
