Question

matt is walking at 1.2 miles per hour to the east. Jaime is walking at 1.2r miles per hour to the south. which statement describes he movement of martt and jaime?

A. They have the same speed but different velocities.

B. They have different speeds but the same velocity.

C. They have different speeds and different velocities.

D. They have the same speed and the same velocity.

Answer 1

C.

Reason: Velocity includes direction, and east vs. south are different directions, so their velocities are different. Their speeds are 1.2 and 1.2r mph; unless r = 1 those speeds differ, so in general they have different speeds and different velocities. (If r happened to equal 1, the speeds would be the same but the velocities would still differ.)
