Study Notes
Understanding Speed and Distance
- A speed of 50 miles per hour means the distance covered in 1 hour is 50 miles.
Converting Time Units
- To convert 30 minutes to hours, divide by 60 (since there are 60 minutes in 1 hour): 30 minutes ÷ 60 = 0.5 hours
Practice Problem Review
Speed and Average Speed
- Average speed is the total distance traveled divided by the total time taken.
Distance and Change in Position
- Distance is the total amount of ground covered, regardless of direction.
- Change in position is the shortest distance between the initial and final points.
- Distance is measured using units such as meters, kilometers, or miles.
- The key difference between distance and change in position is that distance accounts for the entire path taken, while change in position only considers the shortest distance between the starting and ending points.
