t > 8
Step-by-step explanation:
Given that :
Initial volume = 16 litres
Addition rate = 4 litres per minute
Target volume > 48 litres
Let number of minute for which water is added to achieve these = t
Mathematically,
Initial volume + (addition rate * t) > target volume
16 + 4t > 48
Collect like terms
4t > 48 - 16
4t > 32
Divide both sides by 4
4t/4 > 32/4
t > 8
Laura will need add water at 4 Litre per minute rate for more than 8 minutes
