About 26 mins 35 secs (26.6 mins). In 1 minute, Janet will shovel 1/45 of the snow and Bill will shovel 1/65. Thus in 1 minute, working together they will shovel 1/45 + 1/65 = 22/585 of the snow. Thus to shovel all the snow will take: 585/22 minutes = 2613/22 minutes ~= 26 mins 35 secs.

To calculate the hours and minutes worked you could simply start a timer when you get to work and stop it when you leave. Do this every day until it is time to turn in your hours and minutes worked. The amount on the timer will be your total.

5 hours

(worked_it_out_myself)">about 3 hours and 35 minutes (worked it out myself)220 minutes is exactly 3 hours and 40 minutes. 60 minutes (one hour each) times 3 = 180. 40 minutes remain.

The answer will depend on how many days in a week you work. Multiply 2 hours and 40 minutes by that number.

Sue shovels (1/40th) of the driveway each minute.Tom does (1/55th) of the same job each minute.Together, they do (1/40 + 1/55) = (11/440 + 8/440) = (19/440) of the job each minute.It would take them (440/19) = 23.16 minutes to do the whole job together. (rounded)

2.5hrs :) * * * * * Should be :( since that is the WRONG answer - as a simple credibility check on the answer would tell you. If they work together, how can it take longer than Sam doing it alone? Sam can do the driveway in 2 hours so Sam does 1/2 driveways per hour. Max can do the driveway in 3 hours so Max does 1/3 driveways per hour. So Sam + Max do 1/2 + 1/3 = 5/6 driveways per hour. To do 1 driveway would, therefore, take them 1/(5/6) = 6/5 hours = 1.2 hours or 1 hour 24 mintes.

they worked together on the way, they worked together when they were building shelter, and they worked together to deliver letters.
