Question

Which answer is a scientifically accurate description of velocity? Question 5 options: The car traveled 70 mph north to Atlanta on Interstate 75. Walking south along the two-mile canyon trail generally takes less time than traveling the same trail north because walking south is all downhill. The hiker began hiking the park's five-mile north hiking trail at 8:00 a.m. with plenty of daylight left to complete the hike before dark. The motorcyclist traveled along a highway at 55 mph.

Answer 1

Answer:

The car traveled 70 mph north to Atlanta on Interstate 75.

Explanation:

Velocity is the rate at which an object changes position in a specific direction.  It has both magnitude and direction.

So, if you are travelling north at 70 mph, that is your velocity, because you are stating both your speed and the direction.

Walking south along a trail or hiking north give the direction but not the speed.

A motorcyclist travelling at 55 mph gives the speed but not the direction.
