Best ResponseYou've already chosen the best response.0if m = rate of Miguel, then 2m is the rate of maria. Given they work together and fish in 1.5 hrs, we have 1.5 (m + 2m) = 1 m = 2/9. Therefor, the rate of Maria is 2(2/9) = 4/9, thus it will take her 1/ (4/9) = 9/4 hrs to complete the task and 9/4 hours = 2 hrs 15 min
