a biker must circle a 12 mile track twice. His average speed must be 60mph. On his first lap he averaged 50 mph. How fast must h
liq [111]

Answer:

75 mph

Step-by-step explanation:

A biker must circle a 12-mile track twice. His average speed must be 60 mph.

So, the average time required to cover the distance is \frac{2 \times 12}{60} = 0.4 hours.

Now, on his first lap, he averaged 50 mph.

So, he covered this 12 miles track in \frac{12}{50} = 0.24 hours.

Hence, he has to cover the next 12 miles track in (0.4 - 0.24) = 0.16 hours.

Therefore, his average speed in the second round must be \frac{12}{0.16} = 75 mph to qualify. (Answer)

Veronica has two offers for a $65,000 student loan. The first loan has a 6.3% interest rate for 15 years, and the second loan ha
steposvetlana [31]

The second option has a lower amount of interest paid.

In order to determine the loan option that minimizes loan payment, the future value of both loan options has to be determined.

FV = P (1 + r)^nm

FV = Future value  

P = Present value  

R = interest rate  

m = number of compounding

N = number of years  

<em><u>First loan option </u></em>

65000( 1 + 0.063/12)^300 = 312,707.21

<em><u>Second loan option </u></em>

65000( 1 + 0.048/12)^240 = 169,435.51
