You and your friend race from point A to point C. You run from A to B and then from B to C. Your friend runs from A to D and then from D to C. You run at an average rate of 7.8 miles per hour and your friend runs at an average rate of 8.1 miles per hour. Is it possible to determine who wins the race?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

it would rotate about 180 degrees.

they charge the same amount at 20 minutes.
