Astudent rides their bike to school travelling a distance of 1200 meters in 300 seconds. the school is due west of the student’s house. which best represents the speed and velocity of the student?

equation choices:

v = d/t a = (vf-vi)/t

the student’s speed is 4 m east and their velocity is 4 m west.

the student’s speed is 0.25 m/s and their velocity is 0.25 m/s east.

the student’s speed is 4 m/s west and their velocity is 0.25 m/s.

the student’s speed is 4 m/s and their velocity is 4 m/s west.

I believe the correct answer choice would be D. The student's speed is 4 m/s and their velocity is 4 m/s West.

Explanation:

This is because.. I just took the test and it says so XD

In the word problem, it says the student it traveling to school which is west of the students house. It doesn't say anything about East, so you can mark out anything that says "east". (A and B)

Velocity = D/T

I plugged the numbers into the velocity formula: V = 1,200 ÷ 300. I got 4.

Acceleration = (vFinal - vInitial)/T

Acceleration equals the final point of velocity - 1,200, - minus the initial point of velocity (0): 1,200 - 0 = 1,200. That is then divided by the time (300) to get your answer of 4.

Hope this helps,

The student’s speed is 4 m/s and their velocity is 4 m/s West.

Explanation:

Given that,

Distance covered by the student, d = 1200 meters (due west)

Time, t = 300 seconds

To find,

The speed and velocity of the student.

Solution,

Speed is a scalar quantity while velocity is a vector quantity. Speed has only magnitude and velocity has both magnitude and direction. Speed of student is given by :

v = 4 m/s

As the school is due West of the student’s house, the velocity of student is  due west. So, the correct option is (d) "The student’s speed is 4 m/s and their velocity is 4 m/s West".

answer and explanation;

a is the best answer your welcome
