Can anybody help me to solve this problems?

I have a question about hydraulic environment....i hope that u can solve the problem for me if possible. thank you very much.

belowing is the question:
A river receives a discharge of 10 MGD at a concentrattion of 150 mg/l. The river flow upstream is 20 MGD at zero concentration. For 15 mi downstream, the velocity is 10 mpd. A region of slow moving water is then encountered for next 20 mi where the velocity drops to 2 mpd. If the decay rate of the substance is 0.2/day, what is the concentration at the point 35 mi downstream from the outfall?

It is against the policy here to provide solutions to homework problems unless the OP has shown original effort. So if you tell us what you've tried, we can help you along.
