4 and 5 Average

4 and 5 average provides the comprehensive information about what is the average of 4 and 5, and how it is being calculated mathematically. To calculate the average, the given quantities 4 and 5 can be of any physical quantity but both should have been expressed in the same measurement units.

4 and 5 average:
= (4 + 5)/2,
= 9/2,
= 4.5

Hence,
the average of 4 and 5 is equal to 4.5

where,
4 and 5 physical quantities in same measurement units,
9 is the sum of quantities,
2 is the total number of quantities,
4.5 is the average of 4 and 5

The step-by-step work shows how to find what is the average of 4 and 5. The solution for 4 and 5 average is same for all the following queries but have to append the measurement units based on the measurement units of physical quantities being measured.

Unitless Measurement:

Average Speed:
What is the average speed of a bus which covered the distance from point A to B at the speed of 4 mph (miles per hour) and B to C at the speed of 5 mph (miles per hour)?

Average Volume:
The volume of cylinder A is 4 gallons and cylinder B is 5 gallons, what is the average volume of cylinders?

Average Capacity:
A Lincoln theater has the volume of 4 seats and Brooklyn theater has the volume of 5 seats, what is the average capacity of the theaters?

Average Score or Marks:

Solved Example:
what is the average of 4 and 5?

step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 4
Quantity B = 5

What to be found:
Find the average of 4 and 5

step 2 Find the sum of quantities 4 and 5.
4 + 5 = 9

step 3 Find how many number of inputs:
The calculation involves two quantities 4 and 5, so the number of quantities is 2.

step 4 To find the average of 4 and 5, divide the sum of quantities 9 by the total number of quantities 2:
= 9/2
= 4.5
(4 + 5)/2 = 4.5

Hence,
4.5 is the average of 4 and 5.
