Question

If each of the n production workers in a factory assembles one instrument every t minutes, how many instruments does the factory assemble in 7.5 hours of production

Answer 1

The number of instruments assembled in 7.5 hours are 450 n/t.

Explanation:

The number of instruments assembled in t minutes = n

the number of instruments assembled in 1 minute = n / t

Total time = 7.5 hours = 7.5 x 60 = 450 minutes

So, the number of instruments assembled in 450 minutes are

`(n)/(t)* 450\\\\(450 n)/(t)`
