解题思路：若小杰能追上小明，可设追赶时间为x 秒，本题中的等量关系：小明以2米/秒的速度行走经过3秒所行路程+小明以5米/秒的速度行走经过x秒所行路程=小杰以7米/秒的速度行走经过x秒所行路程，据此可列方程组求解．

若小杰能追上小明，设追赶时间为x 秒，则可得方程：2×3+5x=7x，（6分）
解得x=3，（7分）
因为追赶中所在圆圈直径为6米，7x=21＞π×6，
故小杰能在一圈内追上小明．（9分）

点评：
本题考点： 一元一次方程的应用．

考点点评： 本题考查了一元一次方程的应用，相遇问题和追及问题是常见的行程问题，常用的等量关系有：速度和×相遇时间=相遇路程，快者路程-慢者路程=起始相距路程．

丁铃铃,下课了,同学们像小鸟一样飞出教室,参加各种活动.同学们有的赛跑、有的踢键子、还有的跳绳.我最喜欢玩丢手绢.
我们围成一个大圈,我拿起一条花花的手绢开始丢了.我绕着圈走起来,我一边走一边想应该丢给谁.一会儿,我轻轻地放在英华的后面,就若无其事地走了.英华没有觉察,眼看就要被我捉到了,突然,英华转头一看,手绢在她后面,她立刻拿起手绢追我.我飞快地跑到英华的座位坐下.
英华更有办法了,她把手绢捏成团,紧紧地握在手里.慢慢地围着圈子走着,惹得大家不时地回头瞅瞅.这时,她把手绢轻轻地放在蔡宇后面,手又握起来,很多小朋友都上当了,蔡宇输了,蔡宇走到中间为大家唱了一首《时间像小马车》这首歌.
大家玩得可开心了.

跳绳的同学24,丢手绢的同学15

5种活动中选2个共有4+3+2+1=10种
15种都有2个人的时候已经10×2=20人
再来一个人就会出现3人参加一样的活动了
即20+1=21人
