Question

A machine can manufacture 39 units per hour. Assuming 8 hours per day and 5 days per week, the manufacturing time per unit is minutes per unit. Use at least 4 decimals in your calculation and answer

Answer 1

The manufacturing time is 1.5385 minutes per unit.

Explanation:

∵ The units manufactured by machine in 1 hour = 39,

We know that,

1 hour = 60 minutes,

∴ The units manufactured by machine in 60 minutes = 39,

That is,

39 units = 60 minutes,

⇒ 1 unit =
`(60)/(39)`=1.53846153846 ≈ 1.5385 minutes,

Hence, the manufacturing time is 1.5385 minutes per unit.
