SOLUTION: The speed of a stream is 4mph. If a boat travels 58 miles upstream in the same amount of time it takes to travel 29 miles downstream what is the speed of the boat In still Water?

Question 971842: The speed of a stream is 4mph. If a boat travels 58 miles upstream in the same amount of time it takes to travel 29 miles downstream what is the speed of the boat In still Water?

The ques. is wrong. In same amount of time, distance travelled upstream should be less than distance travelled downstream.
So, Solving the ques, by reversing the data as upstream distance=29 miles and downstream distance =58 miles
Let boat's speed in still water = b,
Since time taken upstream = Time taken downstream
=> Distance upstream/ Net speed upstream = Distance downstream/net speed downstream
=>
=>
=>
So speed of boat in still water = 12 mph.
