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.

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=(20mi+20mi+30mi+15mi)/(1h+1h+1h+2h)`

3. Therefore, you have that the result is:

`S=17mi/h`
