Answer:
The total time it takes her to swim the four laps is 3.65 minutes.
Step-by-step explanation:
Here, according to the given data:
The time taken to complete 1st lap = 54.73 seconds
The time taken to complete 2nd lap = 54.56 seconds
The time taken to complete 3rd lap = 54.32 seconds
The time taken to complete 4th lap = 54.54 seconds
Now, the TOTAL TIME taken to swim all 4 laps = SUM OF ALL 4 TIMES
= (54.73 + 54.56 + 54.32 + 54.54) seconds
= 219.35 Seconds
Now, 60 seconds = 1 minute
⇒ 1 seconds = 1/60 minute
⇒219.35 seconds = 219.27 x (1/60) minutes = 3.6558 minutes
Hence, the total time it takes her to swim the four laps is 3.65 minutes.
The interest rates required to get a total amount of $2,420 from compound interest on a principal of $2,000 compounded 1 times per year over 2 years is 10% per year.
<h3>What is compound interest?</h3>
The interest on savings that is calculated on both the initial principal and the interest accrued over time is known as compound interest.
The concept of compound interest, also known as "interest on interest," is thought to have first appeared in Italy in the 17th century. It will accelerate the growth of a sum more quickly than simple interest, which is calculated only on the principal sum.
Money is multiplied more quickly through compounding, and the more times it is compounded, the higher the compound interest will be.
Using the formula A = P(1 + r/n)^nt
Solving for rate r as a decimal
r = n[(A/P)^(1/nt) - 1]
r = 1 × [(2,420/2,000)^{1/(1)(2)} - 1]
r = 0.1
Then convert r to R as a percentage
R = r × 100
R = 0.1 × 100
R = 10%/year
