Answer 2

Calculating Time to Fill the Bathtub

To calculate the time needed to fill the bathtub, we can use the combined flow rate of the hot and cold water taps.

Given: - Flow rate of hot water tap = 16 L/min - Flow rate of cold water tap = 8 L/min - Bathtub capacity = 360 L

Calculation

To find the time needed to fill the bathtub, we can use the formula: \[ \text{Time} = \frac{\text{Volume}}{\text{Flow rate}} \]

First, we need to find the combined flow rate of both taps: \[ \text{Combined flow rate} = \text{Flow rate of hot water tap} + \text{Flow rate of cold water tap} \]

\[ \text{Combined flow rate} = 16 \, \text{L/min} + 8 \, \text{L/min} = 24 \, \text{L/min} \]

Now, we can calculate the time needed to fill the bathtub: \[ \text{Time} = \frac{360 \, \text{L}}{24 \, \text{L/min}} = 15 \, \text{minutes} \]

Answer: It will take 15 minutes to fill the bathtub with both hot and cold water taps running simultaneously.
