I tried to cipher this math problem in my head

If it’s a Chevy, is rpm affected if the alternator is powering both headlights or just 1… assuming the alternator is working to start with?

Why? Cause I want to keep my brain sharp.. I haven't done much math lately and I'm rusty.

How many round trips to work before engine fails?
Will it fail on way home?
How far from home?
Engine fails @ 1 million rpm.
It's 43 miles to work & 43 miles home.
Engine idles @ 500 rpm. Avgs 7 minutes idling each before driving.
70 mph is 2,000 RPM ( less rpm more time)
80 mph is 2,300 RPM ( more rpm less)

i dont think i would worry about the math,,, other than figuring how far away i need to be when she blows! at 1 million rpm thats gonna be a site to see,,,, from a camera a long long ways off!

Just got around to checking and reading the replies.

Yes it's a hypothetical question.
As some have stated I meant 1 million revolutions.

I was wondering where to start with solving this and how factor in the variables.

I used to be good at math.
I could do Algebra in my head and multiply 5 numbers x 4 numbers. That was 30 years ago tho. Math and Reading were my 2 favorite subjects. I would like to build my skills back up.

you need to figure in the revolution changes while accelerating and decelerating also,, is it a 4x4, what is the change when in low range or pulling a load? there really is no answer.... anything would be a guess,,, what about tire slippage on ice or in mud? that changes the distance traveled also and the actual rpm's!

You are way overthinking this

1,000,000 rpms is not a lot for an engine. 2500 rpm @ 60 mphX43 is 215,000 rpms. So 5 round trips will get you past 1,000,000 rpms not including idle time. Get rid of that POS and get a Ram then it might fail at 10,000,000,000 rpms.
