THe wheel has to cover 5 miles, right? So divide the 5miles by the wheel circumference to get the number of turns, and then divide by time.
Can you or someone else please clarify your explanation. Thank you.
What part of Mr. Pursley's explanation don't you understand? He's given you these steps:
Divide the 5 miles by the wheel circumference. That gives you the number of turns.
Divide the number of turns by the time.
I understand what he's telling me to do, but I've gone through it multiple times and it just doesn't seem correct.
What answer did you get?
If I understand the steps correctly, 27x 3.14= 84.78 divided by 5= 16.956 divided by 15= 1.1304 (which seems pretty slow) If you notice a mistake I have made in the procedure please let me know. Thanks
number of turns=5miles/(27inches*PI)
Now, you have to convert miles to inches to divide this out.
Then, after you get revolutions from the above, divide by 15 min to get rev/min
Thank you I appreciate all the help.
