First we need to find the rate of logging for employee A per year. To do this, the number of hours can be divided by the number of years to find out how many hours of travel they log per year.
120 ÷ 4 = 30. Employee A logs roughly 30 hours of travel per year.
To find a percentage increase of 20%, you need to multiply by 1.2. 30 x 1.2 = 36. Therefore, Employee B logs roughly 36 hours of travel per year.
To find out how many hours of travel Employee B logs after 1.5 years, we simply need to multiply 36 by 1.5, which equals 54.
To find out how many hours of travel Employee A logs after 1.5 years, we simply need to multiply 30 by 1.5, which equals 45.
Finally, we need to find out how many MORE hours Employee B logged after 1.5 years compared to Employee A. To do this, we simply need to do 54 - 45 = 9 hours.
Working = (((120/4) x 1.2) x 1.5) - (120/4 x 1.5) Answer = 9 hours.
