Using improper fractions, it is found that they broke the record and were 0.8 minutes faster.
<h3>How to convert improper fractions to standard fractions?</h3>
The conversion is made according to the following formula:
![a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}](https://tex.z-dn.net/?f=a%5Cfrac%7Bb%7D%7Bc%7D%20%3D%20a%20%2B%20%5Cfrac%7Bb%7D%7Bc%7D%20%3D%20%5Cfrac%7Bac%20%2B%20b%7D%7Bc%7D)
In this problem, the time had to be faster than
minutes, which is a time in minutes of:
Researching the problem on the internet, it is found that their time was of
minutes, hence:
![11 + \frac{3}{5} = 11 + \frac{3}{5} = 11 + 0.6 = 11.6](https://tex.z-dn.net/?f=11%20%2B%20%5Cfrac%7B3%7D%7B5%7D%20%3D%2011%20%2B%20%5Cfrac%7B3%7D%7B5%7D%20%3D%2011%20%2B%200.6%20%3D%2011.6)
11.6 < 12.4, hence they broke the record.
12.4 - 11.6 = 0.8, hence they were 0.8 minutes faster.

Answer:
$2465
Step-by-step explanation:
Remember your annual interest rate formula (appreciation): A = P(1 + r)^t
Step 1: Solve for the first 2 years
1900(1 + 0.035)² = 2035.33
Step 2: Solve for the next 4 years
2035.33(1 + 0.049)^4 = 2464.54
