A student is training for the track team during the first three months of the year by running for 30 minutes every day while averaging 5 miles each day. Select the graph that correctly shows the total miles ran during the time of his training program.

The graph is barely visible

OpenStudy (lena772):

I'm sorry I'll make the images bigger..

OpenStudy (lena772):

OpenStudy (lena772):

Is that any better?

hero (hero):

So which graph do you believe is correct?

OpenStudy (lena772):

Hm

hero (hero):

Basically, the graph plots the total miles ran over the total hours spent running

OpenStudy (lena772):

Graph 1 I think

OpenStudy (lena772):

90 days in 3 months 90*5=450 90*30=2700 minutes 2700/60=45 hours

OpenStudy (lena772):

@Hero

OpenStudy (lena772):

or graph 2 idk which axis each should go on

hero (hero):

Okay, good we can talk about that.

OpenStudy (lena772):

:)

hero (hero):

In general, the independent variable is what is plotted along the x-axis. The dependent variable is plotted along the y-axis. The independent variable is almost always going to be time. The dependent variable is going to be the job or something that will be completed over time. In this case miles will be completed over time. So simply, often times they will describe the graph as one of a few things: 1. Miles vs Hours 2. Production (Mileage) over Time (hrs) 3. y/x (y = mileage while x = hours)

hero (hero):

I hope that doesn't confuse you too much

OpenStudy (lena772):

Time is not dependent on anything, everything is dependent on time. So time would be at the x-axis because it is certainly independent. Therefore the answer is B?

hero (hero):

Correct.
