Answers
Answer:
your answer is hast to cut and mold
Answer:
He would complete his work at 2:45 p.m.
Step-by-step explanation:
The time taken for cutting and molding a workpiece is 8 minutes and 13 minutes respectively. The welder has to cut and mold 5 such workpieces.
Time taken to cut and mold 1 workpiece = 8 + 13 = 21 minutes
Time taken to cut and mold 5 workpieces = 21 × 5 = 105 minutes
Therefore, the welder would take 105 minutes to complete his work.
If the welder starts working at 1:00 p.m., he would complete his work at 2:45 p.m. (105 minutes after 1:00 p.m.).
Extra information about time and work:
Time and work is a mathematical concept used to calculate the amount of time required to complete a task, based on the number of workers involved in the task and their efficiency. In this concept, we assume that the efficiency of each worker remains constant throughout the task.
The basic formula for time and work is:
Time taken = (Total work) / (Rate of work)
where rate of work is the amount of work done per unit time by a worker. It is usually expressed in terms of the fraction of work done by a worker in one unit of time, such as one hour or one day.
