Ava wants to figure out the average speed she is driving. she starts checking her car’s clock at mile marker 0. it takes her 4 minutes to reach mile marker 3. when she reaches mile marker 6, she notes that 8 minutes total have passed since mile marker 0.

what is the average speed of the car in miles per minute?

mile(s) per minute

what is an equation of the line that represents n, the number of mile marker passed, as a function of t, time in minutes?

The average speed of car is:

                 0.75 miles per minutes.

The equation of line is:

The table that describes the time and number of  miles marked is given by:

Time       Miles

  0              0

  4               3

  8               6

Clearly we could observe that with the increase in time by every 4   minutes the number of mile increases by 3.

i.e. the average speed is calculated as the ratio of change in miles to the change in time.

Hence,

Hence, the average speed=0.75 miles per minutes.

Also we will find the equation of the lines that related the miles and time by using the two-point formula.

i.e. any line passing through (a,b) and (c,d) is calculated by using the formula:

Here (a,b)=(0,0) and (c,d)=(4,3)

i.e. the equation is given by:

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

step-by-step explanation:

their are no angles. sorry cant .
