甲乙两车同时从两地出发,相向而行,甲车和乙车的速度比是4:3.两车相遇时,乙车行了150千米,甲车行了多少千米?
甲乙两车同时从两地出发,相向而行,甲车和乙车的速度比是4:3.两车相遇时,乙车行了150千米,甲车行了多
少千米?
甲乙两车同时从两地出发,相向而行,甲车和乙车的速度比是4:3.两车相遇时,乙车行了150千米,甲车行了多少千米?
甲 150÷3x4=200千米
折甲车速度为4x则乙车为3x
由于行车时间相同为y
3xy=150 xy=50
有4xy=4*50=200

收起
相遇时间一样,速度比等于路程比;所以可以设甲车行了X千米。列出比例式:X:150=4:3,解得X=200
先求到他们行的时间,时间一定,那么就用甲车的速度去乘以时间。所以答案就是
150÷3×4=200(km)
