A boat can travel with a speed of 13 km/hr in still water.

A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.

Answer/Solution

Steps/Work

Speed downstream = (13 + 4) km/hr = 17 km/hr.
Time taken to travel 68 km downstream = 68/17hrs = 4 hrs.

A boat can travel with a speed of km / hr in still water. If the speed of the stream is km / hr, find the time taken by the boat to go km downstream.

Calculated Answer

Step by Step Solution

In order to solve problem, you must evaluate n₂ / (n₀ + n₁).

n₀ =	13
n₁ =	4
n₂ =	68

n₂ / (n₀ + n₁)
Evaluate n₀ + n₁ = 17
n₂ / 17
Evaluate n₂ / 17 = 4
4
The answer to the problem and the result of n₂ / (n₀ + n₁) is 4
