I think there is enough info there to get to an answer but it will take some assumption. Figure the acceleration rate, then assume that same rate for lap 2?
So if the driver averaged 90 miles per hour for the second lap. What is his average speed for the two laps?
Everything makes sense if you remember that speed is a rate, not an absolute value. This is why I hate the phrase "high rate of speed". A high rate of speed is a rate of a rate, which in this case is acceleration. Just say "high speed."
Exactly how I drive, always. I never "just cruise". It doesn't matter if I have ALL day to do absolutely nothing but go get some milk, when I go get that milk, ill be hauling ass. I cant think of anything in the world that pisses me off more than people that drive like they have nowhere to be and nothing to do. When the light turns green, fucking go. When you get to your driveway, fucking turn in there. When you need to cross traffic and a gap comes, fucking take it. And you don't need to wait till the passing car is 5 lengths past you to initiate your turn-in, you can start turning as they are beside you. One thing that people cant see to get through their heads, the law is "slower traffic keep right", or in some states "keep right except to pass". Nowhere in there does it say "unless you are already going the speed limit". It doesn't matter if the speed limit is 70 and you are going 75...if somebody is behind you being held up, then YOU are slower traffic and need to get the fuck over. So many people will say shit like "but im going the speed limit"...it doesn't fucking matter. You are going slower, so get the fuck out of the way.
The only time I will hover in the passing lane is when I just passed someone going considerably slower and they speed up as I pass. There is no way in hell I'm moving over because they finally decided to go faster.
I hate that shit. You come up on somebody and pass them, then they suddenly decide they want to go faster.
