Mo · Answer 2

Before going to get the answer first we have to understand Vector. A vector is a physical quantity which has magnitude as well as direction for its complete specification.

As per the question the truck is travelling at 30 mph to the west.

Hence the distance covered by the truck in one hour is 50 miles. It is the average speed of the truck. Here 50 mph is the magnitude of the average sped.

The direction of motion of truck is towards west.

Speed is a scalar quantity. But speed in a given direction is called velocity which is a vector quantity.

As per the question the truck is moving 30 mph towards west which infers the velocity of truck whose direction is towards west.

As we know that velocity is a vector quantity, so the quantity described here is a [vector].
