Which statement is a scientifically accurate description of velocity?
The motorcyclist traveled along a highway at 55 mph and reached the campsite in less than the two-hour estimated time.
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.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
