Speed Physics Example 2

Follow the full solution, then compare it with the other examples linked below.

Example 2

easy
Light travels at 3×108 m/s3 \times 10^8 \text{ m/s}. How far does light travel in 1 minute1 \text{ minute}?

Solution

  1. 1
    Convert time: 1 min=60 s1 \text{ min} = 60 \text{ s}.
  2. 2
    d=s×t=3×108×60=1.8×1010 md = s \times t = 3 \times 10^8 \times 60 = 1.8 \times 10^{10} \text{ m}

Answer

d=1.8×1010 md = 1.8 \times 10^{10} \text{ m}
The speed of light is a fundamental constant. At this enormous speed, light covers vast distances even in short time intervals.

About Speed

The rate at which an object covers distance over time, calculated as total distance divided by total time, always expressed as a non-negative scalar quantity.
