SOLUTION: A boat travles upstream in 5 hours and same distance downstream in 3 hours if the speed of boat is 18mph what is speed of current?? 2. A plane x to y afsinst the wind in 8 hour

Question 1038784: A boat travles upstream in 5 hours and same distance downstream in 3 hours if the speed of boat is 18mph what is speed of current??
2. A plane x to y afsinst the wind in 8 hour and flies back from y to x with the wind in 5hrs if the speed of plane is 650mph find the speed of wind?

A boat travels upstream in 5 hours and same distance downstream in 3 hours.
If the speed of boat is 18mph what is speed of current?

RT=D relates speed, time, distance.

SPEED TIME DISTANCE UP 18-c 5 d DOWN 18+c 3 d

Continue to solve for c.

The question #2 is in general the same type or form of example ---- just a different example. The solution process is the same.
