I need some help with a question that i just cant figure out how to solve. I have tried a lot but it does not seem to help. I am looking around and there is some complex math so i am guessing this might be a no brain-er for you guys.
Anyways the question is,
Two Trains travel a 105 km track each day. The express travels 10kmph faster and takes 30 minutes less than the normal train does. Find the speed of the express.
The answer is : 51.1 km/h ( the answer book tells me that)
I need to know how to solve to get to that answer. I cant find a way.
Thanks in advance, please get to me as soon as you guys can.
