Calculated Answer

240

Step by Step Solution

In order to solve problem, you must evaluate (n₀ * n₁ * 2) / n₂.

n₀ =	60
n₁ =	40
n₂ =	20

(n₀ * n₁ * 2) / n₂
Evaluate n₁ * 2 = 80
(n₀ * 80) / n₂
Evaluate n₀ * 80 = 4800
4800 / n₂
Evaluate 4800 / n₂ = 240
240
The answer to the problem and the result of (n₀ * n₁ * 2) / n₂ is 240
