If employee A logged 120 hours of travel in 4 years and employee B logged hours of travel at a 20% higher rate, how many hours did employee b have than employee A after 1.5 years
A's rate = 120 hours/ 4 years = 30 hrs/year
B's rate = 1.2(30) or 36 hours/year
so after 1.5 years, A had 45 hours
and after 1.5 years, B had 54 hours
