(adsbygoogle = window.adsbygoogle || []).push({}); A car moving at 187km/h is behind a truck thats moving at 71km/h and is 150m ahead of the car

How long will it take the car to catch the truck ?

I'm literally in 2 lectures in my physics 101 class but I figure it would be cool to take a shot at the problem. This is what I did...

87km/h - 71km/h = 16km/h

16km/h = 4.4m/s

4.4m/s = 150 / t

t * 4.4m/s = 150

t = 150 - 4.4m/s

t = 146s

Well I checked it on masteringphysics h.w site and it was wrong...can't think of anything else.
