Question

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 more hours did employee B have than employee A after 1.5 years?

Answer 1

rate of logging for a: 120hours/4years
=30hours/year

rate of logging for b = 30+(30x 2) =36
hours/ year

30 hours/ year x 1.5 years = 45 hours

36 hours/ year x 1.5 years = 54 hours
54-45 = 9 hours
