Question

A car is travelling from point A to point B along a straight line. These points are 5 kilometre apart. It takes an hour to cover that distance. Which of the following is correct regarding the speed and type of motion of the car?

• A. Speed= 5 km/hr, non-linear motion
• B. Speed = 5 km/hr, linear motion
• C. Speed = 1 km/hr, linear motion
• D. Speed = 1 km/hr, non-linear motion

Answer 1

The correct option is B Speed = 5 km/hr, linear motion

Given:
Distance= 5 kilometre.
Time = 1 hour.
Since $Speed=\frac{Distance}{Time}=\frac{5}{1}=5km/hr$
Since the car moves in a straight line, it is undergoing a linear motion.
