my answer is 63.56. i don't know if its right answer. here this problem:

It takes Scott an average of 45 min to prune 1 tree. Victor takes 65 min to prune a tree on average. The Scott-Victor Pruning Service has the contract to prune 92 trees in Flagstaff, AZ. How long will it take them to prune all the trees

  • algebra. help!! -

    rate= rate1+ rate2
    rate= 1tree/45min + 1tree/65min= (65+45)/65*45


    time= numbertrees/rate= 92(65*45)/110 in minutes, in hours divide by 60. You are wrong.
