Question

one month ruby worked 6 hours more than issac and svetlana worked 4 times as many hours as ruby together they worked 126 hours find the number of hours each person worked

Answer 1

Answer:

Issac worked for = 16 hours

Ruby worked for = 22 hours

Svetlana worked for = 88 hours

Step-by-step explanation:

Let the time Issac worked be x

The time Ruby worked = x+6

The time Svetlana worked = 4(x+6)

Total time they all worked together = 126hours

According to Question

126 = x + x+6 + 4(x+6)

126 = x + x+6 + 4x+24

126 = 6x + 30

126-30 = 6x

96 = 6x

96/6 = x

16 = x

x = 16

The time Issac worked = 16hours

The time Ruby worked = 16+6 = 22hours

The time Svetlana worked = 4(16+6) = 4×22 = 88hours

Issac worked for = 16 hours

Ruby worked for = 22 hours

Svetlana worked for = 88 hours
