Water from a tap flows into a bath at a rate of 750 ml/s. How long does it
take to fill a bath with 180 ℓ of water?
Answers
Answer:
Four minutes.
Step-by-step explanation:
There are 1,000 milliliters in a liter. So firstly we convert liters to milliliters to liters by multiplying 180 by 1,000, which is 180,000. Then, to find how many seconds it takes to reach 180,000 milliliters at the rate of 750 ml/s, we divide 180,000 by 750. This comes out to the equivalent of 240 seconds, which can be answered as such or simplified to 4 minutes.
1. 180ℓ x 1,000ml = 180,000ml
2. 180,000ml / 750ml = 240s
3. 240s / 60s = 4m
Answer:
It'll take 240 seconds or 4 minutes for the water from a tap to flow into a bath at a rate of 750ml/s with a capacity of 180 litres of water
Step-by-step explanation:
As per the given data, the required eq. is:
time = volume / flow rate
In this case, the volume is given in litres and the flow rate in millilitres per second, so we need to convert the units to ensure they are consistent.
∵ 1 liter = 1000 millilitres
Therefore, the flow rate is 750 ml/s = 0.75 L/s
Now we can substitute the values given in the problem and solve for the time:
time = 180 L / 0.75 L/s
time = 240 sec
∴, it would take 240 seconds or 4 minutes to fill a bath with a capacity of 180 litres of water.
It is important to note that this calculation assumes that the flow rate remains constant throughout the filling process. In reality, the flow rate may vary due to changes in water pressure, so the actual filling time may be slightly longer or shorter than calculated. Additionally, this calculation assumes that there are no leaks or other sources of water loss during the filling process.
