Question

An object be a moving at the starting (0,0) on the graph. Average speed in miles per hour of the object for an entire trip five hours is...

Answer 1

Answer: 17 miles per hour.

Step-by-step explanation:

1. To solve this problem you must apply the following formula:

$S$=Δx/Δt

Where Δx is the position variation and Δt is the time variation.

2. Then, based on the graph shown attached, you have:

$S=\frac{20mi+20mi+30mi+15mi}{1h+1h+1h+2h}$

3. Therefore, you have that the result is:

$S=17mi/h$
