A metal company's old machine makes bolts at a constant rate of bolts per hour. The company's new machine makes bolts at a constant rate of bolts per hour. If both machines start at the same time and continue making bolts simultaneously, how many minutes will it take the two machines to make a total of bolts?

Calculated Answer

108

Step by Step Solution

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

• n₂ / (n₀ / 60 + n₁ / 60)

• Evaluate n₀ / 60 = 1.6666666666667

  n₂ / (1.6666666666667 + n₁ / 60)

• Evaluate n₁ / 60 = 2.5

  n₂ / (1.6666666666667 + 2.5)

• Evaluate 1.6666666666667 + 2.5 = 4.1666666666667

  n₂ / 4.1666666666667

• Evaluate n₂ / 4.1666666666667 = 108

  108
• The answer to the problem and the result of n₂ / (n₀ / 60 + n₁ / 60) is 108
