when we subtract 3 hours, 50 minutes from 5 hours, 20 minutes we get 1 hour, 30 minutes
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
We know that in an hour there are 60 minutes.
1 hour = 60 minutes
We need to subtract 3 hours, 50 minutes from 5 hours, 20 minutes.
In 3 hours 50 minutes we can calculate total number of minutes
3(60)+50
180+50=230
In 5 hours 20 minutes we can calculate total number of minutes
5(60)+20
300+20=320
Now subtract the minus 320 and 230
320-230
90 minutes
90 minutes means 1 hour 30 minutes
Hence, when we subtract 3 hours, 50 minutes from 5 hours, 20 minutes we get 1 hour, 30 minutes

Answer:
Therefore C is not the midpoint of AB.
Step-by-step explanation:
Midpoint: The midpoint is a point from which the distance between the endpoints of a line segment is always equal.
Distance formula:
The distance between the points (x₁,y₁) and (x₂,y₂) is
Given points are A(2,3) and B(-2,5).
If C(0,3) is the midpoint of the line segment AB,then AC=BC.
The distance between AC is
=2 units
The distance between AC is
units.
Since AC ≠ BC
Therefore C is not the midpoint of AB.
