Question

A diver descended 20 feet in 5 seconds. What is the average rate per second that he traveled? Explain how you can use integer tiles to solve the problem and find the answer. Pls help

Answer 1

The diver is moving down, so he moved −20 feet. Start with 20 negative tiles and separate them into 5 equal groups. There are 4 negative tiles in each group, so he traveled at a rate of −4 feet per second.

Explanation:

Answer 2

4 feet per second

Explanation:

We can create a proportion:

`(20)/(5) = (x)/(1)`

Cross multiply:

`20\cdot1=20\\\\20/5=4`

So he's travelling at a rate of 4 feet per second.

Hope this helped!
