Tips

Understanding Average Speed

Average speed is different from instantaneous speed:

  • Average speed considers the entire journey
  • It accounts for stops, slowdowns, and speed changes
  • It's useful for planning and comparing different routes
Tip:
Remember that average speed doesn't tell you about the speed at any particular moment during the journey.
Examples

Practical Examples

Example 1 Road Trip

A car travels 300 miles in 5 hours, including stops.

Average Speed = 300 miles / 5 hours = 60 mph

Example 2 City Commute

A commuter travels 15 miles in 45 minutes (0.75 hours).

Average Speed = 15 miles / 0.75 hours = 20 mph

Example 3 Highway Journey

A truck travels 500 miles in 8 hours.

Average Speed = 500 miles / 8 hours = 62.5 mph
