The speed of a boat in still water is 20 km/hr and the rate of current is 5 km/hr.

The speed of a boat in still water is 20 km/hr and the rate of current is 5 km/hr. The distance travelled downstream in 24 minutes is:

Answer/Solution

10

Steps/Work

Explanation:
Speed downstream = (20+5) kmph = 25 kmph
Distance travelled = (25*(24/60)) km = 10 km.

The speed of a boat in still water is km / hr and the rate of current is km / hr. The distance travelled downstream in minutes is :

Calculated Answer

10

Step by Step Solution

In order to solve problem, you must evaluate (n₀ + n₁) * n₂ / 60.

n₀ =	20
n₁ =	5
n₂ =	24

(n₀ + n₁) * n₂ / 60
Evaluate n₀ + n₁ = 25
25 * n₂ / 60
Evaluate n₂ / 60 = 0.4
25 * 0.4
Evaluate 25 * 0.4 = 10
10
The answer to the problem and the result of (n₀ + n₁) * n₂ / 60 is 10
