The average velocity of the entire trip is 42.5 mph east
An object's average velocity is calculated by dividing its total displacement by its total travel time.
It measures how quickly an object shifts from one location to another.
It is a Vector magnitude
For one hour, an automobile travels 25.0 miles due east.
Then it continues for an extra hour and travels another 60.0 miles east.
We must determine his overall journey average speed.
He does the entire journey going straight east.
He travels a total distance of 25 + 60 = 85 miles east.
He takes an hour to get there from here and another hour to get there from there.
The total travel time is 1 + 1 = 2 hours.
Total displacement times total time equals the average velocity.
His average speed = 85 ÷ 2 = 42.5 miles/hour east
The average velocity of the entire trip is 42.5 mph east
