x | xx | xxx |

G | 25 | xxx |

xxxx is xxx xxxxxxx xxxxx xxxx xx seconds? xx xxxxxxx

xxxxxxxx

Production xxxx xxx day x xxx minutes x 8 xxxxx

Desired xxxxxx rate(r) is xxx xxxxx per day = xxxxx = xx xxxxx xxx hour

Hence, desired xxxxx xxxx in seconds is given by

c x xxxxxxx x **120 **xxxxxxx xxx xxxxx

xxxx is xxx theoretical xxxxxxx number xx stations? xx xxxxxxx

Answer:-

Theoretical minimum, TM x xxxx of all xxxxx xx

x (40+45+55+55+65+40+25)/360

xxxx = xxxxxxx =
