More people working on the same job lessens the number of working hours than when a person works alone.
Step-by-step explanation:
Work Rate:
First secretary: 1/5
Second secretary: 1/4
The job: 1 (typing job)
Number of hours to finish the job: x hours
Working together: 1/x
Equation:
1/5 + 1/4 = 1/xLCD: (4)(5)(x)
(4)(5)(x) [1/5 + 1/4 = 1/x] (4)(5)(x)
4x + 5x = 20
9x = 20
9x/9 = 20/9
x = 20/9
x = 2 ²/₉ hoursOther questions about: Math
