Light travels at 3.0 x 108 km/s. How far does light travel in 5 minutes?

A1.5 x 1010 km
B1.5 x 1011 km
C9.0 x 109 km
D9.0 x 1010 km

Verified Answer :

3.0 x 10^8 km/s is how far light travels.
3.0 x 10^8 km/s x 60s is how far light travels in a minute
3.0 x 10^8 x 60 x 5 is how far light travels in 5 minutes, and you should get D as your answer.

Answer:

D)  \(9*10^{10}\) km.

Step-by-step explanation:

Given : Light travels at \(3* 10^{8}\) km/s.

To find :  How far does light travel in 5 minutes.

Solution : We have given

Light travels in 1 second =  \(3* 10^{8}\) km.

1 minute = 60 second.

5 minute = 60* 5 = 300 second .

Light travels in 5 minute = \(300 * 3* 10^{8}\) km.

Light travels in 5 minute =  \(3*10^{2}* 3*10^{8}\) km.

                                         = \(9*10^{10}\) km.

Therefore, D)  \(9*10^{10}\) km.
