Answer 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.
