Light from the sun reaches earth in 8.3 minutes The velocity of light is 3 x 10¹ meters second How far is the earth from the sun?

Answer 1

Well, the sun is actually 91 million miles away.

But for the purposes of your equation:

Distance = speed x time.

8.3 minutes is 300 seconds.

The speed of light is 186,000 miles per second.

so your equation now looks like this:

Distance = 186,000 x 300.

Therefore distance= 55800000miles

Same calculation, but more accurate:

Well, the sun is actually 93.5 million miles away, on average.

But for the purpose of your education:

Distance = speed x time.

8.3 minutes is 498 seconds.

The speed of light is 187,370 miles per second,

so your equation now looks like this:

Distance = 187,370 x 498.

Therefore distance = 93,300,000 miles.

Answer 2

149,400,000,000 metres

Calculation: 8.3 minutes x 60 is 498 seconds. 498 x 300,000,000 is 149,400,000,000 As it happens, the actual mean distance between the Sun and Earth is about 149,597,900,000 metres (92,955,800 miles) so the approximate values given in the question are pretty close to the real figures.

Answer 3

93,000,000 divided by 186,000 is 500 (seconds). Convert seconds to minutes by dividing by 60.

500 divided by 60 is 8.333 So light from the sun takes just over 8 minutes to reach the earth.

Answer 4

3 x 101 is 30 metres a second.

There are 60 seconds in a minute 8.3 x 60 = 498 seconds

498 x 30 = 14940

By this reasoning and the numbers given the sun is 14,940 metres or 14.94 kilometres from the earth.

[Obviously the sun is much further away than this therefore something is incorrect in the initial statement]

Answer 5

Light from the sun takes approximately 498 seconds (or 8.3 minutes) to reach Earth.
