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:
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:
11.6 < 12.4, hence they broke the record.
12.4 - 11.6 = 0.8, hence they were 0.8 minutes faster.

Answer:
The volume of the water in the tank is 112 m³
Step-by-step explanation:
The volume of the rectangular prism V = L × W × H, where
- L is its length
- W is its width
- H is its height
∵ A rectangular tank has a length of 4 m, a width of 12 m, and
a height of 3.5 m
∴ L = 4 m
∴ W = 12 m
∴ H = 3.5 m
∵ V = L × W × H
∴ The volume of the tank = 4 × 12 × 3.5
∴ The volume of the tank = 168 m³
∵ The tank is filled with water of its capacity
→ That means the volume of the water is the volume of the tank
∵ The volume of the water = the volume of the tank
∴ The volume of the water = × 168
∴ The volume of the water = 112 m³
∴ The volume of the water in the tank is 112 m³
