Answer:
The liters that the tank will contain at 5:11 PM that day are:
- <u>4416 Liters</u>.
Step-by-step explanation:
Firstly, you must identify the outlet flow of the water pumped from the tank, for this, you must subtract the last volume given from the first volume:
- 19,140 L - 8,097 L = 11,043 L
And the minutes that passed from the first volume until the last volume given (18 minutes from 4:47 PM to 5:05 PM), so, you must divide that two values to obtain the outlet flow:
- Outlet flow =
- Outlet flow =
- Outlet flow = 613.5
Now, you must see the next hour given (5:11 PM), if you see, from 5:05 PM to 5:11 PM has passed 6 minutes, taking into account this, you replace the equation of outlet flow to clear the volume:
- Outlet flow =
- Volume = Outlet flow * time
And replace the values to obtain the new volume pumped:
- Volume = 613.5
* 6 min
- Volume = 3681 L.
At last, you must subtract these liters from the last volume identified in the tank:
- New Volume in the tank = 8097 L - 3681 L
- New Volume in the tank = 4416 L
The volume in the tank at 5:11 PM is <u>4416 Liters</u>.
As Given ,
Members play football and basketball = 20
Members play football and vallyboll = 15
Members play basketball and volleyball = 26
Members play all games = x
Members play only one game = 2x
There are total number of members = 110
From above data we can write,
110 = 20 + 15 + 26 + x + 2x + 2x + 2x
110 = 61 + 7x
7x = 110 - 61
7x = 49
x = 7members
To find,
Member play basketboll altogether
= 20 + 26 + 2x + x
We know that x = 7,
= 20 + 26 + 14 + 7
= 67 members
