The time taken for landscaper 1 is 5.4 hours.
The time taken for landscaper 2 is 3.6 hours.
Step-by-step explanation
Let the time taken by the landscaper 1 to complete the job be 'a'
Let the time taken by the landscaper 2 to complete the job be 'a/1.5'
a + (a/1.5) = 9
(1.5a + a) /1.5 = 9
2.5a/1.5 = 9
5a/ 3 = 9
a = 27/5
a = 5.4 hours
a/1.5 = 5.4/1.5
a/1.5 = 3.6 hours
The time taken for landscaper 1 is 5.4 hours.
The time taken for landscaper 2 is 3.6 hours.
