Mean Speed in R.P.M Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mean Speed in RPM = (Maximum Speed in r.p.m. during Cycle+Minimum Speed in r.p.m. during Cycle)/2
N = (N1+N2)/2
This formula uses 3 Variables
Variables Used
Mean Speed in RPM - (Measured in Hertz) - Mean Speed in RPM is an average of individual vehicle speeds.
Maximum Speed in r.p.m. during Cycle - (Measured in Hertz) - Maximum Speed in r.p.m. during Cycle is the number of revolutions the drive shaft of your car is making per minute.
Minimum Speed in r.p.m. during Cycle - (Measured in Hertz) - Minimum Speed in r.p.m. during Cycle is the number of revolutions the drive shaft of your car is making per minute.
STEP 1: Convert Input(s) to Base Unit
Maximum Speed in r.p.m. during Cycle: 22 Revolution per Minute --> 0.366666666666667 Hertz (Check conversion here)
Minimum Speed in r.p.m. during Cycle: 10 Revolution per Minute --> 0.166666666666667 Hertz (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
N = (N1+N2)/2 --> (0.366666666666667+0.166666666666667)/2
Evaluating ... ...
N = 0.266666666666667
STEP 3: Convert Result to Output's Unit
0.266666666666667 Hertz -->16 Revolution per Minute (Check conversion here)
FINAL ANSWER
16 Revolution per Minute <-- Mean Speed in RPM
(Calculation completed in 00.019 seconds)
