Speed Physics Example 1

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

Example 1

easy
A jogger runs 5 km5 \text{ km} in 25 minutes25 \text{ minutes}. What is the average speed in m/s?

Solution

  1. 1
    Convert units: 5 km=5000 m5 \text{ km} = 5000 \text{ m} and 25 min=1500 s25 \text{ min} = 1500 \text{ s}.
  2. 2
    Use the average speed formula: s=dts = \frac{d}{t}.
  3. 3
    Average speed: s=50001500≈3.33 m/ss = \frac{5000}{1500} \approx 3.33 \text{ m/s}

Answer

s≈3.33 m/ss \approx 3.33 \text{ m/s}
Speed is the rate at which distance is covered. Unlike velocity, speed is a scalar and does not include direction.

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.
