I have a question concerning duration. The only resource I can use is a financial calculator, so if you could help me solve this by a financial calculator, that would be much appreciated. The question is as follows:

Find the duration of a 6% coupon bond makingannualcoupon payments if it has three years until maturity and a yield to maturity of 6.7%. What is the duration if the yield to maturity is 10.7%?
