Cars motion

From point A car start at the speed of 90 km/h. Against it departs from the point B at the same time another car at 60 km/h. For how long and where they met if the distance between A and B is 180 km?

Correct result:

t =  1.2 hod
x(A) =  108 km

Solution:

t=180/(90+60)=65 hod=1.2 hod
x(A)=90 1.2=108 km



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
