Acar travels in a straight line covering a total distance of 90.0 miles in 60.0 minutes. which one of the following statements concerning this situation is necessarily true?

E) The average velocity of the car is 90.0 miles per hour in the direction of motion.

Explanation:

From the available options below:

A) The velocity of the car is constant.

B) The acceleration of the car must be non-zero.

C) The first 45 miles must have been covered in 30.0 minutes.

D) The speed of the car must be 90.0 miles per hour throughout the entire trip.

E) The average velocity of the car is 90.0 miles per hour in the direction of motion.

The average velocity of an object is the total distance covered by the object while moving in a particular direction per total time taken to cover the distance.

From the information given, during the course of the journey, the velocity may vary and the acceleration may be zero at some point if the driver of the car decides to stop over.

However, the average velocity for the journey must be 90.0 miles per hour in the direction of the motion in order for the car to be able to cover 90 miles in 60 minutes.

The correct option is E.
