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.

The boat 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.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
