The speed of a car during a trip is represented in the graph. compare distance and displacement at four hours into the trip.

a) the distance traveled is 300 km.
b) distance is 300 km and displacement is 0 km.
c) distance is 300 km/hour and displacement is 300 km.
d) both distance traveled and displacement are 300 km.

The correct option is (D) Both, distance traveled and displacement are 300 km.

Why?

To solve the problem we must remember what distance and displacement means.

Distance means the ground/space covered in a certain time, in physics, distance is equal to the product of the speed and time.

Displacement means the distance between the starting and ending point of an object after (or not) being in motion.

So, for the problem, using the graphic we are asked to find the distance and displacement in 4 hours

We can see that in 4 hours, the distance covered is 300km, also, we can see that the difference (in distance) between the starting point at 0 hours and the ending point at 4 hours is equal to the distance covered in the same time.

Hence, we can see that the correct option is D) Both, distance traveled and displacement are 300 km.

Have a nice day!

wavelength divides in half and speed stays the same.
