Julian is using a biking app that compares his position to a simulated biker traveling julian's target speed. when julian is behind the simulated biker, he has a negative position. julian sets the simulated biker to a speed of 20\,\dfrac{\text{km}}{\text{h}}20 h km 20, space, start fraction, k, m, divided by, h, end fraction. after he rides his bike for 151515 minutes, julian's app reports a position of -2\dfrac{1}{4}\,\text{km}−2 4 1 kmminus, 2, start fraction, 1, divided by, 4, end fraction, space, k, m. what has julian's average speed been so far?

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the answer is 8/21

hope this
