A person walks first at a constant speed of 5.40 m/s along a straight line from point to point and then back along the line from

rosijanka [135]

Answer: The average speed over the entire trip is 3.94 m/s

Explanation:

As we know : $speed=\frac{distance}{time}$

Let the distance of straight line from point to point be = d

Total distance covered = 2d

Time taken to cover the forward journey = $\frac{d}{5.40}$

Time taken to cover the backward journey = $\frac{d}{3.10}$

Total time for the journey = Time taken to cover the forward journey + Time taken to cover the backward journey = $\frac{d}{5.40}+\frac{d}{3.10}$

Average speed = $\frac{\text {total distance}}{\text {total time}}=\frac{2d}{\frac{d}{5.40}+\frac{d}{3.10}}=3.94m/s$

Thus average speed over the entire trip is 3.94 m/s

What is dependent variable?

Schach [20]

Answer:

A dependent variable is a variable whose value will change depending on the value of another variable, called the independent variable.
The variation of a dependent variable is usually the one being researched and studied between the two variable types (dependent and independent). It is done through regression and alteration of inputs and the development of regression models based on theoretical studies.
The dependent variable is dubbed dependent because it is thought to depend in some way on the variations of the independent variable.
