A person invests $6,500 dollars in a bank. The bank pays 6.5% interest compounded continuously. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches $22,600 dollars?

B. 1.8 miles

Step-by-step explanation:

We have been given that Keith left his house, rode his bike 3 miles along one road, took a 90 degree turn, and rode 3 miles to the local swimming pool.

Since Keith turns at a 90 degree, so the given lengths will form a right triangle with each leg equal to 3 miles.

The direct distance between house and pool would be hypotenuse of right triangle.

Take square root of both sides:

The distance covered by the 90 degree angle would be miles.

Therefore, Keith would have saved 1.8 miles, if he had ridden directly to the pool.
