Mr Hoffman a science teacher drove ten miles to school from home in twenty minutes he drove the ten miles home in thirty minutes his average velocity is what?
To calculate Mr. Hoffman's average velocity, we need to consider the total distance traveled and the total time taken. He drove 10 miles to school and 10 miles back home, totaling 20 miles. The total time taken was 20 minutes to school and 30 minutes back, which is 50 minutes. Therefore, the average velocity is calculated as total distance (20 miles) divided by total time (50 minutes), resulting in an average velocity of 0.4 miles per minute.
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
Mr. Hoffman a science teacher drove 10 miles to school from home in 20 minutes. He drove the 10 miles home in 30 min. His average velocity was ms.?
To find Mr. Hoffman's average velocity for the entire trip, we need to calculate the total distance and total time. He drove 10 miles to school and 10 miles back home, totaling 20 miles. The total time taken was 20 minutes to school plus 30 minutes home, which equals 50 minutes (or 50/60 hours). The average velocity (V) is calculated as total distance divided by total time: ( V = \frac{20 \text{ miles}}{\frac{50}{60} \text{ hours}} = 24 \text{ miles per hour} ).
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.

their average speed is greater than their average velocity.

40mph
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! (:

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.
