Problema Solution
maria can shovel snow from her driveway in 35 min. tom can do the same job in 65 min. how long would it take maria and tom to shovel the driveway if they worked together
Answer provided by our tutors
let x = the minutes that Maria and Tom need to finish the job together thus their rate is 1/x
1/35 = the rate of Maria since she can shovel snow from her driveway in 35 min
1/65 = the rate of Tom since he can do the same job in 65 min
1/35 + 1/65 = 1/x
by solving the equations we find
x = 22.75 min
