The fraction 4/5 is equivalent to 0.8 and 80%.
Write 0.8 and 80% as unreduced fractions.
0.8 = 8/10
80% = 80/100
S = 3T - 4
S = 23
23 = 3T - 4
23 + 4 = 3T
27 = 3T
27/3 = T
9 = T......so Travis's rope is 9 ft
Before it charged, the battery was at 23%. In half and hour, it went to 89%. So, it rose 89-23, or 66% in half an hour. Now that we know how much it rose and that there are 30 mins in half an hour, we have to divide 66% by 30 to figure out the answer.
66/30 is 2.2.
So, the battery rose at 2.2% per minute.
Hope this helps!
