Question

A motorcycle moves in a straight line eventually covering a total distance of 75 miles within 60 minutes. Accordingly, which statement below concerning the motorcycle’s movement is inevitably true?

(A) The velocity of the motorcycle is changing

(B) The speed of the motorcycle must be 75 miles per hour through the entire trip.

(C) The first 37.5 miles must’ve been covered in 60 minutes.

(D) The acceleration of the motorcycle must be 0.

(E) The average speed of the motorcycle is 75 miles per hour.

(F) Not enough information is provided to solve this problem.

Explanation / Answer

(E) The average speed of the motorcycle is 75 miles per hour.

because as we don't have enough information, and judging by the case we can say that the average speed of the motorcycle, as we don't know how it's motion changed or any other case

But what conclusion we can make is that vaverage=total distance/total time

Total distance =70miles, total time=1hour

Then vaverage=70/1=70miles per hour
