Practice Speed in Physics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
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 without direction.
How fast you're going, ignoring which way—just the magnitude of motion.
Example 1
easyA jogger runs 5 \text{ km} in 25 \text{ minutes}. What is the average speed in m/s?
Example 2
easyLight travels at 3 \times 10^8 \text{ m/s}. How far does light travel in 1 \text{ minute}?
Example 3
mediumA train travels 120 \text{ km} at 60 \text{ km/h} and then 120 \text{ km} at 40 \text{ km/h}. What is the average speed for the whole trip?
Example 4
mediumA runner completes the first half of a race (5 \text{ km}) at 10 \text{ km/h} and the second half at 15 \text{ km/h}. What is the runner's average speed for the entire race?
