1) what is the total displacement for the 4-hour trip and
2) what is the average velocity for the total trip​

Answer 1

Answer:

We are given that a car travels in a straight line with a velocity of 80 km per hour for 2.5 hours and then the velocity of minus 40 km per hour for 1.5 hours. Here, the total time taken = 2.5 hours + 1.5 hours = 4 hours. Now, we have to find the total displacement of the car. = = 35 km/hr.
