Zhang Cong accidentally knocked over the ink bottle, Be quick. We'll be chasing the score I can't write on this side Here's the supplement In one assignment, you can only see the following words: "a, the distance between the two places is 400km, the speed of motorcycle is 45km / h, and the speed of car is 35km / h? Please complete this question and solve the equation side by side The title is "Zhang Cong accidentally knocked over the ink bottle, so that only the following words can be seen in an assignment:" a, already 400km away, the speed of motorcycle is 45km / h, the speed of car is 35km / h? "? Please complete this question and solve the equation
How many hours do the two cars meet?
Solution: meet for X hours
45X+35X=400
80X=400
X=5
Don't forget to add points
