Question

Light travels 1.08 x 10 9 kilometers in one hour. How far does it travel in 2 hours?

Answer 1

The distance traveled by the light in 2 hours is 2.16×10⁹ km.

Distance:

This is the total length of space between two points covered by an object. Distance has no regard for direction as it is termed a scalar quantity. The S.I unit of distance is meter(m).

To calculate the distance traveled by the light in 2 hours, first, we need to calculate the speed of the light.

Formula:

• S = d/t................. equation 1

Where:

• S = speed
• d = distance travelled

• t = time

From the question,

Given:

• d = 1.08×10⁹ km
• t = 1 hour

Therefore,

• s = 1.08×10⁹/1

• s = 1.08×10⁹ km/h

The distance traveled in 2 hours is

• d = 2×1.08×10⁹
• d = 2.16×10⁹ km

Hence, the distance traveled by the light in 2 hours is 2.16×10⁹ km
