HELPPPPPPPPPPP!!!!!!!

Answer 1

Answer:

2.5 hours

Step-by-step explanation:

900 litres = 5 hours

450 litres = x hours

INVERSE VARIATION

a1 : a2 :: b1 : b2

900 : 450 :: 5 : x

Product of extremes = product of means

900x = 450 × 5

x = 450 × 5

900

x = 2.5 hours

Answer 2

Step-by-step explanation:

This can be solved by unitary method.

ATQ,

900 litre takes = 5 hours

1 liter takes = 5 / 900

450 liter takes = 5 / 900 × 450

= 2.5 hours or 2 hours 50 minutes
