I tried to cipher this math problem in my head

[adam_p]

43 miles / 70 MPH = 0.614 hours per trip
0.614 * 60 minutes = 36.857 minutes per trip
36.857 * 2000 RPM = 73,714.2857 driving RPM
73,714.2857 + (500 RPM idle * 7 minutes idle time) = 77,214.2857 total RPM per trip
1,000,000 / 77,214.2857 = 12.951 trips before failing

12.9 Trips @ 70 MPH so it'll fail on the way to work
11.9 Trips @ 80 MPH so it'll fail on the way home

Na, one trip is to and fro. to work would be <.5 to home would be >.5

1,000,000 / 77,214.2857 = 12.951 trips before failing

round trip is 86 miles.

43 is one way.

half your numbers.

You forgot to take in to account the time it takes him to get to and from 70mph (80).

And OP forgot to include the color of his left fender, because that would have cleared it right up.

Driving your commute at 70mph is more efficient, in terms of fewer motor revolutions per day.

Driving your commute at 70mph:
73.71 minutes at @2000RPM =147,420 revolutions
7 minutes @500RPM =3,500 revolutions

Driving your commute at 80mph:
64.5 minutes at @2500RPM =161,250 revolutions
7 minutes @500RPM =3,500 revolutions

70 MPH Commute = 147,240 + 3,500 =150,920 revs per commute
80 MPH Commute = 161250 + 3,500 =164,750 revs per commute

This of course excludes the range of speeds accelerating and decelerating.

In other words... PURPLE

FANTASTIC JOB

Not an F! Based on the info given its the best approximation one could surmise. You're having to operate under the assumption that the truck instantly goes from idling to 70 mph and there is no acceleration nor deceleration at any point during the trip.

I’m coming up with 5 1/2 and 152. Oh hold on, what was the question?

Pffft...everyone knows that it's always 3.5 and 120

Burt Reynolds died.

Say it isn't so!!!

Hangin' round the trailer shop by myself

And I had so much time
To sit and post about myself

And then there it was
Like tachometer mental pie

Yeah there it was
Like speedo superfly

I smell math and candy here

Who's that laughing at my missing hair?

Who's that casting devious threads in my direction?

Trailer boss this surely is a dream

Yeah online date this surely is a dream

Yeah hunters this surely is a dream.

You da man, Chew

No it is not.

The vehicle will never reach 1,000,000 RPMs. Its simply not possible, no engine, internal combustion or jet turbine can turn 1,000,000 RPMs.

[SB09]

I'd like to see an engine that is turning at 1mil RPMs...

Good job, my brain started singing along 1/2 way through.


WOT is the only way to run an engine, it gets the oil pump pushing the oil harder which extends engine life.
That and some Slick-50 will screw your math all up.

No way to know without knowing tire pressure and what direction.

did yall hear that fat joe left atlantic?

Although it was stated 1 million rpms, I believe he meant the engine would fail after 1 million revolutions. While this is a hypothetical problem, think about this: at 70 mph running at 2000 rpm’s, your engine is turning 120,000 revolutions each hour you drive. So let’s say by some magical phenomenon, you only drive 70 mph. It would take 8.33 hours or 583 miles before the engine revolves 1 million times. 70 mph @ 2,000 rpms for 100,000 miles - the engine revolves 171,428,571 times.

Ok - back to doing math I get paid to do…

I see where you are coming from and I think my mind like most everyone else's when to 1mm R's
