Question

В 18 веке город Брюссель снабжал кружевами королевские дворы всей Европы. Для королевского двора Франции изготовили 15 кружевных воротников. На плетение одного воротника уходило 48 часов. Сколько дней понадобилось трём кружевницам, чтобы выполнить этот заказ, если они работали по 12 часов в день?

Answer 1

1) 48:12=4 (дня) уходит на плетение 1 воротника
2) 15:3=5 (в.) сделает 1 кружевница
3) 5*4=20  (дн.) понадобиться на изготовление 15 вортничков

Answer 2

Calculation of Time Needed to Complete the Order

To calculate the number of days it took for three lacemakers to complete the order of 15 lace collars, we need to consider the following information:

- Each collar took 48 hours to make. - The lacemakers worked 12 hours per day.

To find the total number of hours needed to complete the order, we multiply the time it takes to make one collar by the number of collars:

48 hours/collar * 15 collars = 720 hours

Since three lacemakers were working on the order, we divide the total number of hours by the number of lacemakers:

720 hours / 3 lacemakers = 240 hours

To convert the total number of hours to days, we divide by the number of hours worked per day:

240 hours / 12 hours/day = 20 days

Therefore, it took the three lacemakers 20 days to complete the order of 15 lace collars, assuming they worked 12 hours per day.
