Which answer is a scientifically accurate description of velocity? a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish. b. the motorcyclist traveled southeast along a highway at 55 mph and reached the campsite in less than the two-hour estimated time. c. 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. d. walking south along the two-mile canyon trail generally takes less time than traveling the same trail north because walking south is all downhill.

B. The motorcyclist traveled southeast along a highway at 55 mph and reached the campsite in less than the two-hour estimated time.

Explanation:

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

Travelling southeast at 55 mph is a velocity. It gives both speed and direction.

Statements A., B., and C. give the direction but not the speed.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
