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:

A complete description of motion should include distance, direction, and time. The hiker's motion has all three - 2 miles (distance), north (direction), and 30 minutes (time). The ballerina's motion lacks direction, Bobby's lacks time and direction, and the turtle's lacks distance and direction details.

Answer:

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