Homework Statement
If you walk to school at 4 mph and jog home at 6mph, what was your average speed?
Homework Equations
S = D/T
The Attempt at a Solution
Is the average speed not just (4 + 6)/2 = 5mph ?
If not, why not?
4 miles in totalmjc123 said:Work it out. Suppose the school is 2 miles away. How far have you traveled there and back? how long did it take? What was your average speed?
Average speed is the total distance traveled divided by the total time taken to cover that distance. It is a measure of how fast an object is moving on average.
To calculate average speed, divide the total distance traveled by the total time taken. The result will be in units of distance per unit of time, such as miles per hour or kilometers per hour.
No, average speed and instantaneous speed are different concepts. Average speed is a measure of the overall average rate at which an object is moving, while instantaneous speed is the speed at a specific moment in time.
Average speed is important in science because it allows us to quantify the rate at which objects are moving. This is useful in many fields of science, such as physics, chemistry, and biology.
Yes, average speed can be negative if the object is moving in the opposite direction of the chosen positive direction. For example, if an object travels 10 meters south in 5 seconds, its average speed would be -2 meters per second, indicating it is moving in the negative direction (south) at a rate of 2 meters per second.
