Question

A worker is allowed half an hour personal time in a normal 8-hour shift. If the normal time for manufacturing a product is 5 minutes, the standard time (in seconds) is .............

Hint:

When calculating standard time, remember to include allowances for personal, rest, and delay times, and convert the result into the desired units.

Answer 1

To calculate the standard time, we need to account for both the normal time and the allowances. The formula for standard time is: \[ {Standard Time} = {Normal Time} \times (1 + {Allowance}) \] Here, the normal time for manufacturing a product is 5 minutes. - The worker is allowed 30 minutes of personal time in a normal 8-hour shift. The total shift time is 480 minutes (8 hours), and the allowance is \( \frac{30}{480} = 0.0625 \) or 6.25%. Now, calculate the standard time: \[ {Standard Time} = 5 \times (1 + 0.0625) = 5 \times 1.0625 = 5.3125 { minutes}. \] To convert this to seconds: \[ 5.3125 \times 60 = 318.75 { seconds}. \] Thus, the standard time lies between 315 and 325 seconds.
