Part 1: How long does it take to reach your goal if the rate is 7.65%?

Part 2: What Interest rate would you need to reach your goal in 6 years?

For part 1 I got 6.68 years, which I'm pretty sure is wrong, and if it isn't then I donno how I got it. I'm totally lost on part 2, I know I'm supposed to use P=ert for both, right? Could anyone walk me through this?
