在比例尺为1:50000的图上,8厘米的线段表示实际距离(
)米
一条公路长36千米,画在比例尺为1:600000的图上,应画(
)厘米。
解决问题
在一幅比例尺是1:2000000的地图上,量的甲、乙两城市之间的高速公路的距离是5.5厘米。在另一副比例尺为1:5000000的地图上,这条公路的图上距离是多少?
甲、乙两件商品的价格比是7:3,如果他们的价格分别上涨70元后,价格比为7:4,这两种商品原来的价格各是多少元?
甲从A地出发,以每分钟70米的速度像B地驶去,行驶了全程的20%以后,乙每分钟80米的速度从B地出发,与甲相向而行,12分后两人相遇。A、B两地间的路程是多少米?
一幅地图,图上2.5厘米表示实际距离75千米,这幅地图的比例尺是(1:3000000
)
在比例尺为1:50000的图上,8厘米的线段表示实际距离(40000
)米
一条公路长36千米,画在比例尺为1:600000的图上,应画(
6)厘米。
1.
设这条公路的图上距离是xcm
1:5000000=x:(5.5×2000000)
x=2.2
2.设甲原来的价格是7x元,那么乙就是3x元
(7x+70):(3x+70)=7:4
x=30
这两种商品原来的价格分别是
7x=7×30=210
3x=3×30=90
3.(70+80)×12÷(1-20%)=2250(米)
