Light from the sun travels to Earth at a speed of 1.86 × 105 miles/second. How much time will the light take to cover a distance of 9.2 × 107 miles? Write your answer in scientific notation, and round so the first factor goes to the hundredths place.

Respuesta :

The time it would take the light to cover the distance is 4.95 × 10² seconds

Calculating time

From the question, we are to determine the how much time light will take to cover the given distance

The given distance is

9.2 × 10⁷ miles

From the given information, we have that

speed of light = 1.86 × 10⁵ miles/second

Using the formula,

Speed = Distance / Time

Then,

1.86 × 10⁵ = 9.2 × 10⁷ / Time

∴Time = 9.2 × 10⁷ / 1.86 × 10⁵

Time = 4.95 × 10² seconds

Hence, the time it would take the light to cover the distance is 4.95 × 10² seconds
