Solve

Calculated Answer

60

Step by Step Solution

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

• n₀ / (n₀ / n₁ - n₂ / 60)

• Evaluate n₀ / n₁ = 1.5

  n₀ / (1.5 - n₂ / 60)

• Evaluate n₂ / 60 = 0.5

  n₀ / (1.5 - 0.5)

• Evaluate 1.5 - 0.5 = 1

  n₀ / 1

• Evaluate n₀ / 1 = 60

  60
• The answer to the problem and the result of n₀ / (n₀ / n₁ - n₂ / 60) is 60
