To compare: The practice run by two students John and Dante during cross country practice.
Answer to Problem 75SGR
John did a 50 minute run and Dante did a 55 minute run during cross country practice.
Explanation of Solution
Given information:
The graphical representation of practice run of John is provided below
Practice run of Dante is described as, he leaves for high school and runs at a steady rate for 18 minutes until he reaches middle school which is about 3.2 miles away. He runs around 10 laps around the track in middle school in 14 minutes. Then he runs back to high school to complete 55 minute run.
Formula used:
The graph of a function is said to be linear is it is straight line. If it is a curve it is non-linear.
When the graph of the function lies above the x -axis the function is said to be positive otherwise negative.
When the graph of the function goes up it is an increasing function when viewed from left to right otherwise function is decreasing.
Calculation:
Consider the graphical representation of practice run of John is provided below
Practice run of Dante is described as, he leaves for high school and runs at a steady rate for 18 minutes until he reaches middle school which is about 3.2 miles away. He runs around 10 laps around the track in middle school in 14 minutes. Then he runs back to high school to complete 55 minute run.
Recall that the graph of a function is said to be linear is it is straight line. If it is a curve it is non-linear.
Observe that for both John and Dante the graph is non-linear. Total time by John is 50 minutes and by Dante is 55 minutes. Both reaches the middle school at the same time. John complete 10 laps around the track in middle school in 9 minutes.
