Answer:
His average velocity was 0 miles per hour
Explanation:
Answer:
His average velocity was 0 miles per hour
Explanation:
The average velocity of an object is its total displacement divided by
the total time taken
It is the rate of changes of its position from one place to another
Average velocity is a Vector quantity
Its SI unit is meters per second
Mike ran ten laps around his school's 1/4 mile track in 15 minutes
He finishes his run at the exact same point that he started
That means he ran 10 laps of 1/4 mile each in 15 minutes
We need to find his average velocity in miles per hour
Then we must change 15 minutes to hour
1 hour = 60 minutes
15 minutes = hour
He ran 10 lap each lap is 1/4 mile
The distance he ran = miles
But his displacement is zero because he finished his race at the
same point of starting
The average velocity = total displacement ÷ total time
Total displacement = 0 miles
Total time =
The average velocity = 0 ÷ = 0 miles/hour
His average velocity was 0 miles per hour
