LET’S DRILL!
A car travels from point A to B in 3 hours and returns back to point A in 5 hours. Points A and B are 150 miles apart along a straight highway. Which of the following statements most accurately describes the motion of the car? Please choose from one of the following options. • The total displacement of the trip is 300 miles. • The car travels at 50 mph for the first half and 30 mph for the second half. • The average speed is 37. 5 miles per hour. • The average velocity is 40 miles per hour.
The displacement is the shortest distance from the initial to the final position. Since we start and end at the same place, displacement is zero.
The average velocity is calculated with the displacement over time, which would also be zero.
The car could travel at any velocity or speed since we only know it traveled 150 miles in 3 hours. The velocity could have oscillated back and forth from 90 mph to 10 mph or remain constant at 50 mph.
So the answer is? ? ?

Exit Slip 1. On the back of the “What are independent and dependent variables” worksheet; yes, the one we just did our drill problem on, tell me 3 things you can do to find the answer to your 3 questions you had from the speed and velocity video you wrote in your notebooks? 2. What do speed, velocity, mass and weight have in common?
