Answer:

speed of light = 3 x 10^8 meters / second There are 3,600 seconnds per hour so,

speed of light = 3 x 10^8 meters / second * 3,600 = 1.08 x 10^12 meters / hour

1.496 x 10^11 meters ÷ 1.08 x 10^12 meters/hour = .1385 hours which rounds to

.139 hours  

Step-by-step explanation:

The time taken by light to travel from the sun to the earth is 0.139 hours and this can be determined by using the formula of speed.

Given :

  • The distance from the earth to the sun is 1.496 x [tex]10^{11}[/tex] meters
  • The speed of light is 3 x [tex]10^8[/tex] meters per second.

The following steps can be used in order to show that light will take 0.139 hours to travel from the sun to the earth:

Step 1 - Remember in 1 hour there are 3600 seconds.

Step 2 - So, the speed of light in m/hour is:

[tex]=3\times 10^8\times 3600[/tex]

[tex]=1.08\times 10^{12}[/tex] m/hour

Step 3 - So, the time taken by light to travel from the sun to the earth is:

[tex]\rm t = \dfrac{1.496\times 10^{11}}{1.08\times 10^{12}}[/tex]

Step 4 - Simplify the above expression.

t = 0.139 hours
