It will take 10 years and 197 days.

Explanation:

Giving the following information:

You invest $180 in a mutual fund today that pays 6.80 percent interest annually.

To calculate the time required to double the money, we need to use the following formula:

n=[ln (FV/PV) ]/ln (1+r)

n = [ln (360/180) ] / ln (1.068)

n = 10.54

To be more accurate:

0.54*365 = 197

It will take 10 years and 197 days.
