1 yard in 6 minutes

Question 1
Part A

Find the unit rate.

Answers

The unit rate is 1 yard :: 6 minutes. This is correct because you cannot divide each number evenly.

The unit rate in feet per second is 1/120 feet/sec.

Given that, 1 yard in 6 minutes.

What is the unit rate?

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

We know that 1 yard=3 feet and 1 minute = 60 seconds

Now, 6 minutes = 360

So, unit rate is 3/360

= 1/120 feet/sec

Therefore, the unit rate in feet per second is 1/120 feet/sec.

Step-by-step explanation:

We do change in y over change in x

Formula for Rate of Change on Slope

y2-y1/x2-x1

For Y

We use coordinate (-2, -4)

-4--2

= -2 - -4

= 2

For X

We use coordinate (0, -4)

0 -- 4

= 0 + 4

= 4

Now we put y over x to find the rate of change in slope

2/4, simplified would be 1/2
