Final answer:
Calculating the time required to cut 2.4m steel tubes into 5mm sections and flatten them reveals the process will finish at 11:17 AM, given each washer takes 4 seconds to make and the process starts at 10:45 AM.
Step-by-step explanation:
The question involves calculating the time required to process a length of steel tubes come in 2.4m length into washers. Considering each tube is cut into 5mm sections and it takes 4 secs to make a washer, we can first determine the total number of washers that can be made from one tube.
To find this, we convert the length of the tube to millimeters:
Then, divide the total length by the length of each section:
- 2400mm / 5mm = 480 washers
Now, since each washer takes 4 seconds to make:
- 480 washers x 4 secs/washer = 1920 seconds
Converting seconds to hours, minutes, and seconds:
- 1920 seconds = 32 minutes
Assuming the process of flattening at 10:45, we can add the 32 minutes to this start time:
- 10:45 AM + 32 minutes = 11:17 AM
Therefore, the process will finish at 11:17 AM.
