Answer: <em>time = 55.48 years</em>
Explanation:
Given:
Principal amount = $10000
Interest rate = 2% p.a
Amount = $30000
We can evaluate the time taken using the following formula:
![Amount=Principal(1+\frac{r}{100})^{t}](https://tex.z-dn.net/?f=Amount%3DPrincipal%281%2B%5Cfrac%7Br%7D%7B100%7D%29%5E%7Bt%7D)
![30000 = 10000\times(1+\frac{2}{100})^{t}](https://tex.z-dn.net/?f=30000%20%3D%2010000%5Ctimes%281%2B%5Cfrac%7B2%7D%7B100%7D%29%5E%7Bt%7D)
Solving the above equation, we get
![1.02^{t} = 3](https://tex.z-dn.net/?f=1.02%5E%7Bt%7D%20%3D%203)
Now taking log on both sides, we get;
![t\ log(1.02) = log(3)](https://tex.z-dn.net/?f=t%5C%20log%281.02%29%20%3D%20log%283%29)
<em>time = 55.48 years</em>
Distance equals velocity times time.
d=vt
v=d/t
v=(3*2/5)km/5min
v=(6/5)/5
v=6/25 km/min
v=0.24 km/min
