hours. Working alone, Pam takes three times as long as Shirley. How long does it take Shirley to mow the lawn alone?

Answer :

The time it would take Shirley to mow the lawn alone is 3 hours

How to determine the value

From the information given;

Let Shirley's working hours be x

Let Pam's working hours be y

We have  that;

Shirley and Pam work 6 hours together, this is expressed as;

x + y = 6

Given that Pam work 3 hours alone, we have;

y = 3

Substitute the value of y as 3 in the equation

x + 3 = 6

x = 6 - 3

x = 3

Thus, the time it would take Shirley to mow the lawn alone is 3 hours
