please answer ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It takes 20 sec to fill ten-litre bucket with water. what is the rate of flow in litres per hour?
20 sec to fill ten-litre bucket with water
60 / 20 = 3
3 x 10 = 30 litres per hour ?
im prett sure that's wrong
10 L in 20 sec
so 30 L in 60 sec or 30 L per minute
so 30(60) L in 1 hour
1800 L / hour
To find the rate of flow in liters per hour, we need to convert the time taken from seconds to hours and the volume from liters to liters per hour.
First, let's convert the time taken from seconds to hours:
20 seconds = 20/60 minutes (1 minute = 60 seconds)
20/60 minutes = 1/3 hours (1 hour = 60 minutes)
Now, let's find the flow rate in liters per hour:
The bucket is filled with 10 liters of water in 1/3 hours.
To calculate the rate, we divide the volume by the time:
Flow rate = Volume / Time
Flow rate = 10 liters / (1/3 hours)
To divide by a fraction, we multiply by the reciprocal of the fraction:
Flow rate = 10 liters * (3/1 hours)
Flow rate = 30 liters per hour
Therefore, the rate of flow is 30 liters per hour.
