Read the word problem below. chan rows at a rate of 8 mph in still water. it takes him three hours to row upstream from his house to the park. he rows back home, and it takes him two hours. what is the speed of the current? which of the following is a clue that would solve this word problem? the rate of chan’s rowing in still water is 8 mph. chan rows from the house to the park. chan rows back from the park to the house. the entire trip takes five hours.

The clue is , Chan rows back from the park to the house.

Step-by-step explanation:

According to the question,

It takes him three hours to row upstream from his house to the park.

And, He rows back home, and it takes him two hours

Thus, the total time taken by him = 5 hours.

Also, the speed of boat = 8 mph

Let the speed of stream = y mph and the total distance from house to park = x miles

When it is given that, Chan rows back from the park to the house.

That is, the distance in both upstream and downstream will be same.

Then,   and  

By solving these two equations,

We get, x = 8/5 mph and x=19.2 miles

Thus, the speed of stream = 8/5 mph or 1.6 mph

Note: The other data already given in the question.

Therefore, we can not consider them a clue.
