Re: The impossible hill
Seems pretty simple to me, you have to go down the other side backwards at 240mph. That way you wouldn't use up any time at all
Actually if you do that won't you get to the other side before you started?

Re: The impossible hill
It seems that you cannot maintain an average speed of 60 mph, unless you blast a hole in the hill with a big laser beam. Then you could do it by maintaining a level roadway and not having to go up the hill.

Re: The impossible hill
I'm just going to put the Brown Crown in neutral on the down side and do my best to break the sound barrier at the bottom

Re: The impossible hill
One, whether or not it is horizontal or up and down a hill, the distance is measured by the odometer not the horizontal distance. In every mathematical situation not all answers are possible, so the fact it took you two minutes to get to the top you can never reach an average of 60 MPH, lets assume that the maximum speed you can go in your vehicle is 120 MPH that say you would cover the final mile downhill in 30 Seconds so your total time is 2.5 minutes, so would cover 1.25 miles (on average) in one minute, so the maximum average MPH would be 48 MPH. You would have to go the final mile in an instance which is impossible, so the problem posed by IJ is impossible.
Just my 2 cents

No problem. The bus won't do 30 mph uphill! On the other hand, if I were driving the jeep, I wouldn't be going that slow up the hill.... nor that slow going down the hill either.

Re: The impossible hill
Iceni John left in a school bus driving toward the lake one hour before Crazy Cal. Cal drove his school bus in the opposite direction going 6 mph slower then John for one hour after which time they were 174 mi. apart. What was John's speed?
60 mph "He had a tail wind"

60 mph

The only reason I was going slower is I haven't done any mods to my engine yet. Just you wait.

There is, as you clearly stated, zero time left to complete the downhill portion of the trip. What is required in order to complete the task successfully is a portal into a wormhole in the time/space continuum at the top of the hill, into which the bus plunges, arriving sanguinely at the assigned destination at the exact moment it had reached the hilltop.
Maybe it's the old Indiana Jones sequel we watched this weekend talking, not me . . . . .
