Answer 1

The time formula for simple interest is:

`t=(I)/(Ci)`

Where I is the interest, C is the capital and i is the rate

In this case, we have:

I= 867

i=6.8%

C=17000

Replace and solve:

`t=(867)/(17000*0.068)`
`t=0.75\text{ years}`

The time is 0.75 years because the rate is in years.

Convert years to months:

`0.75years*(12months)/(1years)=9\text{ months}`
