# 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?

Result

t =  1.2 hod
x(A) =  108 km

#### Solution:

$t=180/(90+60) = \dfrac{ 6 }{ 5 } = 1.2 \ \text{ hod }$
$x(A)=90 \cdot \ 1.2 = 108 \ \text{ km }$
