Velocity = Distance ÷ Time
Average Velocity = (10 + 10) ÷ (1/3 + 1/2) = 20 ÷ 5/6 = 20 x 6/5 = 24 mph
NOTE : The times in minutes have been converted into fractions of an hour to enable the answer to be provided in miles per hour.

Mr Hoffman a science teacher drove 10 miles to school in 20 minutes He drove the 10 miles home in 30 min His average velocity was?
zero
A science teacher drove 10 miles to school in 20 minutes He drove the 10 miles home in 30 min His average velocity was ms?
He drove 20 miles in 50 min. so average was 20 x 60/50 = 24 mph
Jake and Brenda drove at a speed of 30 mph for 1 hour. Then they turned around and drove 45 mph until they were back where they started. What is true about their average speed and average velocity?
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
Mr Hoffmana science teacher drove 10 miles to school in 20 minutes He drove the 10 miles home in 30 min His average velocity was?
Well, speed is equal to distance over time (s = d/t) However, velocity means speed WITH direction. This means that the teacher's drive to school would be a positive velocity, but the drive back would be a negative one. Now, let's calculate velocities using the s = d/t formula! Distance to school from home: speed = distance/time speed = +10 miles/20 minutes speed = 1/2 miles per minute Distance from school to home: speed = distance/time speed = -10miles/20 minutes speed = -1/3 miles per minute Note: the velocity towards home will be negative since we are travelling in the opposite direction of the distance to school (which is positive) We have our two velocities- let's calculate the average! 1/2 -1/3 = 1/6 1/6 divided by 2 = 1/12 Thus, our average velocity is 1/12 miles per minute! You can convert this into decimal values if required. Hope this helped! (:

Jake and Brenda drove at a speed of 30 mph for 1 hour Then they turned around and drove 45 mph until they were back where they started What is true about their average speed and average velocity?
their average speed is greater than their average velocity.

What is the average speed of a car if you drove 20 miles in 30 minutes?
40mph
How velocity use in a sentence?
Velocity basically just means speed. We drove at a high velocity down the highway.
Rachel drove 174 miles in 180 minutes What was her average speed in miles per hour?
Her average speed was 58 miles per hour.
You went to school your 1997 chrysler sebring 2.5 v6 drove fine after school you went to start your car and the battery was dead a friend gave you a jump you drove about 30 minutes and got home dead?
You need a new battery or a new alternator.
Why is average velocity independent of the route taken?
Velocity is a measure of speed, in distance over time. The route or distance travelled is independent because it bears no relevance. For instance, if one person drove 50 miles at 50 miles per hour the trip would take one hour. If another drove 100 miles at 50 miles per hour the trip would take two hours. In these two instances the routes are different, the times the trip takes are different but the velocity ( 50 mph ) is the same.
