Question

The graph shows a proportional relationship between the number of kilometers traveled (y) and the number of minutes spent traveling (x).

What is the unit rate, expressed in kilometers per minute?

Answer 1

`4(1)/(6)\ \text{kilometers per minute}`

Explanation:

The graph shows a proportional relationship between the number of kilometers traveled (y) and the number of minutes spent traveling (x). This graph passes through the point (75,30). This means that in 30 minutes (x = 30), it was traveled 75 kilometers.

To find unit rate, divide the number of kilometers by the number of minutes:

`(75)/(30)=(25)/(6)=4(1)/(6)\ \text{kilometers per minute}`
