Relative speed is 25+5+15-5 = 40
Distance is 300
Time to meet = 300/40 = 7.5

It is usually best to start word problems by breaking them down into bite-size pieces (a Precise approach).
We know that:
speed of water from A to B is 5mph
distance from A to B is 300 miles
Boat P starts from A at 25mph speed
Boat Q starts from B at 15mph speed
Question: How many hours pass until the boats meet?
Once we have all the info organized in a nice and clear fashion it is very easy to set up the equations:
Boat P speed * time = 300 - Boat Q speed * time
30t = 300 - 10t --> 40t = 300 --> t = 300/40 = 7.5 hours.
(D) is the answer
*Note that the above equations added the speed from the stream to P and subtracted it from Q, but this is wholly unnecessary: the effects of the stream are symmetrical so cancel out.
