I made a image in my head. Then I counted the spaces it took me to get from one point to the next.
1. y+5=-x-5
2. y=-x-5-5
3.y=-x-10
4. y=x-10
_______________________

Distance can’t be negative so add the distance and it’s 19m time is 11min distance/time is velocity her velocity was 1.72m/min
Given :
A = 25000
P = 20000
r % = 9.6 % = 0.096
n = 12
To Find :
The time taken say t.
Solution :
We know, compound interest is given by :
Taking log both sides :
Hence, this is the required solution.
