I think it is the first one.
slope, rate of change is.
use this formula, to find right of change we can.

input two pairs of coordinates, we must.
use 0, 1 and 5, 4, we will.
4 - 1 / 5 - 0
3 / 5
3/5, the slope is.
hmm.
convert 3/5 to decimal, we must.
multiply both sides by 2, we can.
3 * 2 = 6
5 * 2 = 10
6/10, our new fraction is.
convert to decimal, we must.
6/10 = 0.6
0.6, our slope is.

Step-by-step explanation:
a day =24hrs so 10 days=240hrs
20hrs/240hrs ×100%to get the percentage
20/240×100%=8 1/3
