Answer:

13.2 minutes or 13 minutes 12 seconds.

Step-by-step explanation:

1. Count how much water drains the first pump every minute. Let the volume of pool be D. Every minute first pump drains D/11 water.

2. Working together(6 minutes) First pump drains 6D/11 water, hence the second pump drains 5D/11 water.

3.Count how much water drains second pump per minute -> (5D/11)/6= 5D/66

4. It takes the second pump 66 minutes to drain pool 5 times, thus it takes 13.2(66/5) minutes to drain the pool, which is 13 minutes 12 seconds.

You can convert a temperature given in degrees Celsius to Fahrenheit temperature by using the expression 9x ÷ 5 + 32, where x is
Minchanka [31]

Water freezes at 32 degree Fahrenheit.

Step-by-step explanation:

Given,

Formula for Celsius to Fahrenheit = \frac{9}{5}x+32

x = Celsius temperature

Boiling point of water = 0°C

We will put x=0

0°C = \frac{9}{5}(0)+32

0°C = 0+32

0°C = 32 degree Fahrenheit

Water freezes at 32 degree Fahrenheit.
