A car travels a total distance of 150km. At the 50 minutes mark the car has travelled 50km and at the 110 minutes the car has tr
Nitella [24]

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:

\bar v=\dfrac{\Delta X}{\Delta t}=\dfrac{(120-50)\, km}{(110-50)\, min}=\dfrac{70\,km}{60\,min}\\\\\\\bar v=1.667\dfrac{km}{min}*\dfrac{1\,min}{60\,s}*\dfrac{1000\,m}{1\,km}=19.44\dfrac{m}{s}

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

the variable z is directly proportional to x. when x is 6, z has the value 18. what is the value of z when x = 10 the variable z
nikklg [1K]
Z\alpha x
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\alpha  \frac{1}{x}
z=\frac{a}{x}
Where x is a constant of proportionality,
when x=3, z=2
2=\frac{a}{3}
a=3*2
a=6
When x is 13,
Z=\frac{6}{13}

Each person on a boat ride pays $26 for a ticket.There are 63 passengers.How much money is collected from all the passengers?
dezoksy [38]
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.
