The speed of a boat in still water in 42 km/hr and the rate of current is 3 km/hr.

The speed of a boat in still water in 42 km/hr and the rate of current is 3 km/hr. The distance travelled downstream in 44 minutes is:

Answer/Solution

33 km

Steps/Work

Speed downstream = (42 + 3) = 45 kmph
Time = 44 minutes =44/60 hour = 11/15 hour
Distance travelled = Time × speed =11/15×45 = 33 km

Calculated Answer

33

Step by Step Solution

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

n₀ =	42
n₁ =	3
n₂ =	44

(n₀ + n₁) * n₂ / 60
Evaluate n₀ + n₁ = 45
45 * n₂ / 60
Evaluate n₂ / 60 = 0.73333333333333
45 * 0.73333333333333
Evaluate 45 * 0.73333333333333 = 33
33
The answer to the problem and the result of (n₀ + n₁) * n₂ / 60 is 33
