A child drove a remote control car on a a tile floor for a distance of 1.6 m. The graph represents the motion of the car. Pay attention to the fact that this graph has speed and time instead of distance and time on the x and y axis. Which description of motion is best represented by this graph?
The speed of the car is constant.

The mass of an unidentified rock is 15.5 grams. Students determine the volume of the rock by placing the rock in a cylinder with water. The students calculate the density of the rock. They determine the identity of the rock based on the density ranges in the table. The students most likely have which type of rock?
Peridotite
