工程队挖一条水渠,计划每天挖100米,24天完成,实际提前4天完成,实际平均每天挖多少米?
100×24÷(24-4)
=2400÷20
=120(米)

2、一辆汽车从甲地到乙地,前3小时行了156千米,照这样速度,从甲地到乙地共需8小时,甲、乙两地相距多少千米?(用比例解)
156/3 :x/8
解:3 x=156×8
X=416

3、有两条绸带,第一条长6.2米,第二条比第一条的2倍少0.2米,两条绸带共长多少米?
6.2+(6.2×2-0.2)
=6.2+12.2
=18.4(米)

X+4/5 X=54
9/5 X=54
X=30
30×4/5=24

5、修一条路,第一施工队单独修要4天完成,第二施工队单独修要6天完成,如果两队合修,几天可以修完这条路的?
1÷(1/4+1/6)
=1÷5/12
=2.4(天)

6、在比例尺是1:4000000的地图上,量得甲、乙两地相距20厘米,两列火车同时从甲、乙两地相对开出、甲车每小时行55千米,乙车每小时行45千米,几小时后相遇?
20/ X:1/4000000 80000000厘米=800千米
1 X=20×4000000 800÷(55+45)
X=80000000 =8(小时)

7、一个圆锥形稻谷堆,底面半径是1米,高1.5米,每立方米稻谷约重600千克,这进修进修堆稻谷重多少千克?
1×1×3.14×1.5×1/3×600
=3.14×1.5×1/3×600
=4.71×1/3×600
