(30/5)*2+1=13小时
解释,第一小时大客车比小汽车快30千米,因小汽车每小时增加5千米,那么到（30/5）+1=7小时时,两车速度相等,那么要再经过30/5=6小时时小客车的速度比大客车快30千米,故小汽车需要（ 13 ）小时追上客车

Once the third overall choose this season, candidates may McKee Lang

McGee, Washington
According to "Washington Post" reported how the recent news how the Minnesota Timberwolves signed second place with their own wish to have no. 6 Washington Wizards, and Javier - Mackey. But "Washington Post" well-known correspondent Michael - Lee has stated that the Wizards have completely no interest.
Lately,wholesale ray ban sunglasses, a source said the Timberwolves desire to sign handle their second location Washington Wizards center McKee no. 6 pick. Nevertheless the Wizards have said,wholesale kids shoes, if related towards the young 7-foot 1-inch-tall center, they don't even bother to speak about. Wizards that, although he's indeed desire a greater choose within the draft pick, however, if related to Mackey's, then a whole factor would merely not within the scope of discussion - the addition to the Wizards, the league still many teams believe that Mackey, the 23-year-old center if this election, then your choose will be set in the fundamental 3-5. Thus, McKee,wholesale headphones, no. 6 choose for second place to sign, no different with the No. 6 choose and third overall for second location sign sign, that is clearly not worthwhile.
Wizards clearly recognize that, with McKee in exchange for rookie isn't worth - Wizards Mackey has been training for 3 a number of now finally emerging, offers to be a great center. Scarce in the current large league center environment, Mackey this talent is very rare. And the Wizards also think that even though only No. 6 pick, they certain can help the c's elected to some rookie. Minnesota isn't a secret you want to do business, they already have the previous games - Michael Beasley and Kevin - Lufkin. Place show preferred Derek - Williams,wholesale Oakley, although strong,wholesale sunglasses, but with slightly Minnesota repeat the current system, so following the workout, Minnesota touches on Ernest - Kantor can also be really interested.

设X小时追上，此时：
客车行驶距离为：90X千米；
小客车行驶距离：60+(60+5)+（60+5*2)+。。。+（60+5*（X－1)）＝60X+5*（1+（X－1)）/2 ＝60X+2.5X*（X-1)
二者距离相等，所以：90X＝60X+2.5X*（X-1)
整理得：2.5（X-1)=30
解得：X＝13
即，13小时后追上。...
