Question

which example provides the most complete description of an objects motion?
the ballerina rotated 10 times in 2 minutes.
the hiker followed a road heading north for 2 miles in 30 minutes.
bobby threw a ball 10 meters through the hoop.
the turtle took 20 minutes to make it to the other side of the road.

Explanation:

To completely describe an object's motion, we need to know distance, direction and time. The hiker example gives distance (2 miles), direction (north) and time (30 minutes). The ballerina example only has rotation count and time. Bobby's ball - throw only has distance. The turtle example only has time and reaching a destination without direction and specific distance details.

Answer:

The hiker followed a road heading north for 2 miles in 30 minutes.
