Item 9 a flight averages 460 miles per hour. the return flight averages 500 miles per hour due to a tailwind. the total flying t
Ksenya-84 [330]

Let us say that the variables for flight is designated by 1, while the return flight by 2, since the distance travelled are equal, therefore:

v1 t1 = v2 t2

or

460 t1 = 500 t2

 

Since t1 + t2 = 4.8, therefore: t1 = 4.8 – t2

460 (4.8 – t2) = 500 t2

2208 – 460 t2 = 500 t2

960 t2 = 2208

t2 = 2.3

 

t1= 4.8 – t2 = 4.8 – 2.3

t1 = 2.5

 

Answer:

The flight took 2.5 hours while the return flight took 2.3 hours.

You have decided to start saving for college and open up a 529 account. You invest $5,000 into the account at a 2% interest rate
raketka [301]

You will have $5,525.39 after 5 years.

Because the interest is compounded monthly, you need to convert the interest rate and the term of investment to a monthly basis.

Monthly interest = 2% / 12 = 2/12%

Term of investment = 5 x 12 = 60 months

To find the amount you will have in 5 years, use the formula:

<em>Future value = Amount * ( 1 + interest) ^ term of investment </em>

= 5,000 x ( 1 + 2/12%)⁶⁰

= $5,525.39

In conclusion, your investment will have compounded to $5,525.39 in 5 years.
