8km - 24 minutes, to find the unit rate (how long it took to run 1km)
We would make a ratio,
8:24
Now just simplify,
8:24
=
1:3
Therefore the unit rate would be 1 kilometer covered for every 3 minutes.

Answer: 300 percent
Step-by-step explanation:
Where: 15 is the old value and 60 is the new value. In this case we have a positive change (increase) of 300 percent because the new value is greater than the old value.
This question is based on greatest common factor.
There are 45 red buttons and 60 yellow buttons
factors of 45 = 3,5,15
factors of 60 = 2,3,4,5,6,12,15
Hence the highest common factor is 15
Narci can use 15 boxes to divide buttons equally.
She can divide 45 red buttons in 15 boxes by putting 3 buttons in each box.
She can divide 60 yellow buttons in 15 boxes by putting 4 buttons in each box.
