Question

Len is planning a three-hour trip down the Allenem River and back to his starting point. He

knows that he can paddle in still water at 3 milh and that the rate of the current is 2 milh.
How much time can he spend going
downstream?

Answer 2

Len can spend 2 hours going downstream on the Allenem River.

Step-by-step explanation:

Total trip down = 3 hrs

Rate of current = 2 milh

Rate of still water = 3 milh

To calculate the time Len can spend going downstream, we need to consider the combined velocities of Len and the river current.

Since the current is moving at 2 milh and Len can paddle at 3 milh in still water, his effective velocity downstream is the sum of these velocities, which is 5 milh.

Since Len is planning a three-hour trip, he should spend two-thirds of this time going downstream.

Therefore, Len can spend 2 hours going downstream.
