The problems states as follows: A car traveling at 88 km/h is 110 m behind a truck traveling 15 km/h. How long will it take the car to reach the truck? I attached my solution to the
problem, which is incorrect; though it is wrong, I was just wondering if any one could provide their interpretation of my attempt at this problem--that is, what did I actually solve for?

While your method is correct, you have calculated the truck speed incorrectly. Truck speed is 15 kph not 75 kph.

I am dreadfully sorry, I copied down the problem wrong; the speed of the truck is supposed to be 75 km/h

What did you arrive at for a time?

I got 30.6 s--which is actually the answer. Well, this is rather embarrassing; I must have made some algebraic error the first time around calculating it, because I am getting the correct answer now. Sorry everybody, and thank you for your help.
