Jasmine is running faster.

Since the track is 1/5 of a km and she can run 1km in 7 minutes, divide seven to get 1.4.

This means that Jasmine can run one lap in 1.4 minutes.

Since a Kyah can run 6 laps in 10 minutes, do 10 divided by 6 and the answe will be 1.6 repeating.

1.4 < 1.6 so Jasmine is faster

1400 dollars is placed in an account with an annual interest rate of 5.5%. to the nearest year, how long will it take for the ac
olga_2 [115]

It will take 19 years and 6 months for the account value to reach 2900 dollars

Step-by-step explanation:

Given

Principal amount = 1400 dollars

Rate = 5.5 %

Final value = A = 2900

We have to find t

So,

The formula for simple interest is:

A = P(1+rt)

Putting values

2900 = 1400(1+0.055.t)\\\frac{2900}[1400} = 1+0.055t\\2.071 = 1+0.055t\\2.071-1=0.055t\\1.071 =0.055t

Dividing both sides by 0.055

\frac{0.055t}{0.055} = \frac{1.071}{0.055}\\t = 19.47\ years

Rounding off to nearest tenth

19.5 years

Hence,

It will take 19 years and 6 months for the account value to reach 2900 dollars
