Homework Statement
There is one car which got stolen which goes from the point 30 in the negative sense of the "x" axe towards the point 0 and has a constant speed of 160 km/h. Another person notices the stealing 3 minutes later and takes another car to catch the stealer. What must be the minimal speed fo the car to catch the stealer before he reacher the point 0 ? (This is all one dimension, btw)[/B]
Homework Equations
average speed on x = delta x / delta t[/B]
The Attempt at a Solution
I found the following two equations :
-160= (x -22)/t (The stealer reaches the point 22 3 minutes later)
Vx= (x-30)/t (The guy who notices he got stealer)
I don't know what to do at this point :/ A hint would be good. Thank you
