C is on the line and D is not on the line.
-1/2(-40)+1=21
-1/2(20)+1≠-11
Answer:
The flow rate in dextrous solution is 0.117 litres per hour
Step-by-step explanation:
Given:
The volume of fluid which passes per unit time = 1.17 Litres
Time Period = 10 hour
To Find:
The Flow rate per hour = ?
Solution:
Flow rate is defined as rate at which the "{volume of fluid which passes per unit time"
Here the Flow rate is = 
On substituting the values
The Flow rate is =
The flow rate is 0.117 litres per hour
Thus 0.117 litres of dextrous solution flows per hour.
