Basic math HELP! Confused?

if one worker can lay 50 tiles per hour, how many tiles do you think 2 worker can lay ? 100 i think

dont you think so ?

how many can 3 workers lay per hour ? 150 i think which is 3 * work done by one worker

thats why we have 3 workers

simple , isnt it ?

so one worker in one hour is 50 tiles

3 workers in one hour is 3 * 50 = 150 tiles

3 workers in 8 hours or 1 day is 150 * 8 = 1200 tiles

no of tiles as per your calculation is 12,800

so number of days is 12 800 /1200 which is 10 and two thirds of a day

all the best

As you're saying, you have 12,800 tiles are required to be laid As you have 3 workers laying 50 tiles in step with hour for 8 hours an afternoon 3 x 50 x 8 = a million,2 hundred tiles laid in step with day subsequently 12,800 / a million,2 hundred 10.66667 or 10 Days, 5hours, 20 minutes

1 worker can lay 50 tiles per hour

3 workers can lay 150 tiles per hour = 8*150=1200 tile per day

so 12,800/1200=10 2/3 days.

You have 3 workers working 8 hour days, meaning the total work done in a day is 24 hours worth (3x8).

Then you would divide 256 by 24 and get 10.666667, which means that it will take 11 days.

Assuming each worker does the same amount of work that would be 150 tiles laid per hour * 8 hours per day = 1200 tiles laid each work day.

12800 tiles / 1200 tiles per workday = 10.667 days They would be done on the afternoon of the 11th day.

Hey devide 12800 tiles by 150 tiles per hour for 3 workers

50 x 8 =400 per worker

400x3=1200 each 8 hours

12800 / 1200 = 10.66667 days =)

You were almost there. One worker can do it in 256 hours, so 3 workers can do it in 1/3rd the time:

time for 3 workers = 256/3 = 85.33 hours

Now convert this into days (i.e. 8 hour chunks):

number of days for 3 workers = 85.33/24 = 3.555 days. A little over 3 and a half days.

6in x 6in = 1/4 sq ft

50 tiles x 1/4 = 12.5 sq ft per hr per man

12.5 sq ft x 3 men = 37.5 sq ft per hr

37.5 sq ft x 8 hrs = 300 sq ft total per day

80 ft x 40 ft = 3200 sq ft

3200 sq ft / 300 sq ft = 10.67 days

read 6 in x 6 in and my head started to hurt. sorry
