Need to convert mph to rpm. How to do it? See below please.
Step-by-step explanation:
assume statute mile of 5,280 ft or 1760 yards
(
35
m
p
h
60
)
= miles per minute = 0.583333 miles per minute
Now how many ft in 0.58333 miles?
1 mile is 5 280 ft thus
0.58333mile * 5 280 ft/mile = 3 080ft
Circumference of wheel is C=
π
d
C = 26*
π
C

81.681 inches /12 = 6.807ft/revolution
Now how many times does the wheel rotate in one minute?
3
080
f
t
minute
/ 6.807 ft/revolution = 452.489 rpm
