6th grade math, help me please.

(B) 1:2

Step-by-step explanation:

Looking at this, we can add to get 50, the total amount of minutes spent exercising.

Now, we can also see that Arnold spent 25 minutes lifting weights.

So he spent of his time lifting weights.

That fraction is just a ratio.

Let's simplify that fraction.

or 1:2.

So the ratio of the minutes lifting weights to the entire workout is 1:2.

Hope this helped!

is there any attachment? what are the equations?

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
