Answer:
The average velocity is 19.44 m/s.
Step-by-step explanation:
The average velocity between two points can be calculated with the following formula:

The procedure is to calculate the difference for both distance and time, and dividing the two differences, we get the average velocity.
Z

Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30
Part B;
Z

z=

Where x is a constant of proportionality,
when x=3, z=2
2=

a=3*2
a=6
When x is 13,
Z=
180 degrees. It would be half of the circle.
Since there are 63 passengers and it is $26 for each passenger,you have to do 63 x $26. 63 x $26 = $1638,so $1638 was collected from the passengers.
Its C! Hope this helps and can you mark me as brainliest :))
