Tinh can row at a rate of 6 mph in still water. it takes her 2 hours to row upstream from a dock to a park. she then rows back to the dock, and it only takes 40 minutes. what is the speed of the river current?

The speed of the river current = 3mph

Step-by-step explanation:

Let x be the speed of the river current.  

Given: The speed of Tinh in still water = 6 mph

Let d be the distance from dock to park.

Now, speed in upstream = 6-x

Time taken in upstream = 2 hours

Distance covered upstream =....(1)

Speed in downstream = 6+x

Time taken in downstream = 40 minutes =hour= 2/3 hour

Distance covered downstream =.....(1)

From (1) and (2), we have

Hence, The speed of the river current = 3mph

8121 because

130,000 divided by 16 is 8121

answer: slight chance that it will happen
