You decide to enter in a rowing competition. to train, you go to the boat house and begin rolling down stream. you row for the same amount of time upstream and downstream, travel down stream for 2400 m, but only one sixth that distance upstream. the current travels at a rate of 10 m/s. what is the time you spend rowing down stream? how fast would you be rolling in stillwater?

Time spent rowing down stream

Speed of boat in still water

Step-by-step explanation:

Let speed of boat in still water be

Speed of current

Speed of boat down stream =

Distance rowed down stream = 2400 m

Time spent rowing down stream = =

Speed of boat up stream =

Distance rowed up stream =

Time spent rowing up stream =

We know that,

So,

Cross multiplying

Dividing both sides by

Adding 60 to both sides.

Subtracting both sides by

Dividing both sides by 5.

∴

Speed of boat in still water

Time spent rowing down stream =

for b its (t) and c its (d)
