Question

You and a friend race each other. You give your friend a 50-foot head start. The distance y (in feet) your friend runs after x seconds is represented by the linear function y=14x+50 . The table shows the distances you run.

Time (seconds) x : 2, 4, 6, 8
Distinct (feet) y : 38, 76, 114, 152
A. what is the rate per second.
B. Write a linear function that relates your distance to the number of seconds. In the same coordinate plane, graph the linear functions that represent the distances of you and your friend.

Answer 1

Explanation:

You run faster than your friend and the rate is 19

Answer 2

The answer is 19. To find the rate of distance, it is distance divided by time. For the second one, plug in the numbers. And btw, I have this question and am in 7th grade.
