 Question 176675: car travels around a 1 mile oval track at 30mph. The same car does a second lap, how fast does the car need to travel to aveage 60mph for both laps in 2 minutes? Answer by Edwin McCravy(8999)   (Show Source): You can put this solution on YOUR website!A car travels around a 1 mile oval track at 30mph. The same car does a second lap, how fast does the car need to travel to aveage 60mph for both laps ``` 60mph is 1 mile in 1 minute or 2 miles in 2 minutes. 30mph is half that, 1 mile in 2 minutes, so since 2 minutes have already elapsed, he'd already have to have finished the 2 laps in those 2 minutes it's taken him to just finish the first lap. So he can't possibly average 60mph, even if he could go at the speed of light! Maybe you don't understand that. If not look at it this way: Let's figure out how much time it took the car to travel the first mile lap at 30mph Now lets figure out how long it would take the car to travel both laps, averaging 60mph: There is no way he can average 60mph for the two laps, because he has already used up the whole of a hour just to make the first lap.
