1. Answer:

   a) 2160 chips

   b) 2 hours 13 minutes

   Step-by-step explanation:

   Given –

   chips prepared in 40 minutes = 360

   To find –

   a) the number of packs of chips in 4 hours

   b) the time taken to prepare 1200 packs of chips

   Solution –

   a)

   Chips prepared in 40 minutes = 360

   Chips prepared in 1 minute = 360/40 = 9

   Chips prepared in 4 hours = chips prepared in 240 minutes (4×60 min)

   = 9×240 chips

   = 2160 chips

   So chips prepared in 4 hours = 2160 chips.

   b)

   360 Chips are prepared = 40 minutes

   1 chip prepared = 40/360 minutes = 1/9 minutes

   1200 chip prepared = 1200×1/9 minutes

   = 1200/9 minutes

   = 133.33 minutes

   So 1200 chips will prepare in 133.33 min (approx 2 hours 13 min)

   hope it helps.
