The grand prix formula 1 race this weekend is in singapore. the race consists of 61 laps
around a 5.067 km long track. at 225 miles per hour, how long will it take to go around
once?

Distance = 5.067km -> 5067m
Time = ?
Speed = 225 miles/h > Convert either by using an online converter or use this 10miles -> 16093.44m, therefore (225x16093.44)/10 = 362102.4m then hours to minutes which needs to be divided by 3600. 360102.4/3600= 100.584m/s

Distance = Speed X Time
Time = Distance/Speed
Time = 5067/100.584
         = 50.3758053s

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
