Earth is approximately 1.5x10^8 km from the sun. how many minutes does it take to travel from the sun to the earth? the speed of light is 3x10^8 m/sec



Answer :

Distance of earth from the sun = 1.5 x 10⁸ km
speed of light = 3 x 10⁸ m/s 
time in minutes = ?
by using the formula,
Distance = velocity x time, we get
time = distance/velocity
time = t = (1.5 x 10⁸) / (3 x 10⁸) = 0.5 seconds
convert 0.5 seconds to minutes = 0.00833333
it takes 0.00833333 minutes to travel from the sun to the earth

Answer:

8.33 minutes will it take to travel from the sun to the earth.

Step-by-step explanation:

Distance of the Earth from the Sun = d = [tex]1.5\times 10^8 km[/tex]

1 km = 1000 m

[tex]1.5\times 10^8 km=1.5\times 10^8 \times 1000 m=1.5\times 10^{11} m[/tex]

Speed of the light, s = [tex]3\times 10^8 m/s[/tex]

Time taken by the light to travel from the sun to the earth = T

[tex]Speed=\frac{Distance}{Time}[/tex]

[tex]s=\frac{d}{T}[/tex]

[tex]T=\frac{d}{s}=\frac{1.5\times 10^{11} m}{3\times 10^8 m/s}=500 s[/tex]

1 min = 60 seconds

T = 500 s = [tex]\frac{500}{60} min=8.33 minutes[/tex]

8.33 minutes will it take to travel from the sun to the earth.
