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.
Explanation:
Velocity is the rate of change of displacement with time. It is a physical quantity that has both magnitude and direction.
When expressing velocity, we must consider the directional attribute as it distinguishes it from speed.
Statements:
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.
We are given the displacement of the hiker but the duration of traveling was not indicated. The starting time is known and there is nothing we can infer from it
The motorcyclist traveled along a highway at 55 mph and reached the campsite in less than the two-hour estimated time.
55mph is the speed of the motorcyclist and not velocity. There was no directional attribute.
Walking south along the two-mile canyon trail generally takes less time than traveling the same trail north because walking south is all downhill
This is not quantifiable.
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 200m marker north is the displacement and the time is 5minutes. This is the most scientifically accurate description of velocity.

Answer:
Secondary structure
The secondary structure arises from the hydrogen bonds formed between atoms of the polypeptide backbone. The hydrogen bonds form between the partially negative oxygen atom and the partially positive nitrogen atom
Answer:
0.41s
8.01m/s
Explanation:
Using the formula; v = u + at
Where;
u = initial velocity (m/s)
v = final velocity (m/s)
t = time (s)
a = acceleration (m/s²)
According to the provided information, u = 4m/s, s = 8m,
V = u + at
4 = 0 + 9.8t
4 = 9.8t
t = 0.41s
b) v = u + at
v = 4 + 9.8(0.41)
v = 4 + 4.018
v = 8.018m/s
