Walking at the rate of 4 kmph a man cover certain distance in 2 hr 45 min.

Walking at the rate of 4 kmph a man cover certain distance in 2 hr 45 min. Running at a speed of 16.5 kmph the man will cover the same distance in.

Answer/Solution

40 min

Steps/Work

dist = 4*22/4 = 22km
new speed = 16.5 kmph
=>D/S = 11/16.5 = 40 min

Calculated Answer

40

Step by Step Solution

In order to solve problem, you must evaluate (n₀ * (n₁ + n₂ / 60)) / n₃ * 60.

n₀ =	4
n₁ =	2
n₂ =	45
n₃ =	16.5

(n₀ * (n₁ + n₂ / 60)) / n₃ * 60
Evaluate n₂ / 60 = 0.75
(n₀ * (n₁ + 0.75)) / n₃ * 60
Evaluate n₁ + 0.75 = 2.75
(n₀ * 2.75) / n₃ * 60
Evaluate n₀ * 2.75 = 11
11 / n₃ * 60
Evaluate 11 / n₃ = 0.66666666666667
0.66666666666667 * 60
Evaluate 0.66666666666667 * 60 = 40
40
The answer to the problem and the result of (n₀ * (n₁ + n₂ / 60)) / n₃ * 60 is 40
