Question

A machine fills 600 bottles in three minutes.

How long does the machine take to fill 900 bottles?

Answer 1

Answer:

time taken for 1 bottle = 3/600 or 180/600 ( 3mins=180 secs)

so time taken by 1 bottle=3/10 secs.

time taken for 900 bottles=3/10*900

= 270 secs or 4.5 minutes

Answer 2

Step-by-step explanation:

Machine fills 600 bottles in 3 minutes

Same machine fills 900 bottles in x minutes

600 / 3 = 900 / x

2700 = 600 x

2700 / 600 = x

27 / 6 = x

x = 4.5

Machine fills 900 bottles in 4.5 minutes
