a car travels 25 miles at 25 miles per hour (mi/h), 25 miles at 50 mph, and 25 miles at 75 mph. Write a program to find the arithmetic mean of the three velocities and the harmonic mean of the three velocities. Which is correct? R programming"
Answers
a car travels 25 miles at 25 miles per hour (mi/h), 25 miles at 50 mph, and 25 miles at 75 mph.
- First speed a1 = 25
Second-speed a2 = 50
Third-speed a3 = 75
Difference, d= a3-a2 = a2-a1= 25
Nth tem of Ap = a+(n-1)d
= 25+(n-1)25= 25n
- For harmonic series, the difference between reciprocals of numbers should be constant but here it is not same.It is following the property of ap.
- Hence the given numbers in AP.

Answer:
The correct answer of this question is 25n
Explanation:
Given - A car travels 25 miles at 25 miles per hour (mi/h), 25 miles at 50 mph, and 25 miles at 75 mph.
To Find - Write a program to find the arithmetic mean of the three velocities and the harmonic mean of the three velocities.
A automobile goes 25 miles per hour (mi/h), 50 miles per hour (mph), and 75 miles per hour (mph).
First speed is a1 = 25
And Second speed is a2 = 50
Then, Third-speed a3 = 75
Difference mean of the three velocities d = a3 - a2 = a2 - a1 = 25
Nth term of Ap = a + ( n - 1 ) d
5 + (n-1) 25= 25n
The difference between reciprocals of numbers should be constant in harmonic series, however it is not in this case. It is adhering to the ap attribute.
