How long does it take to fill a tank with a volume of 2 cubic meters using a bucket with a capacity of 8 liters if filling the bucket and pouring it into the tank lasts 18 seconds.
Task data: V1 (tank volume) = 2 m3; V2 (bucket capacity) = 8 l (in SI V2 = 8 * 10-3 m3); t1 (duration of filling the bucket and pouring it into the tank) = 18 s.
The time taken to fill the tank can be determined by the formula: t = n * t1 = V1 / V2 * t1.
Let’s calculate: t = 2 / (8 * 10-3) * 18 = 4500 s = 75 minutes = 1 hour 15 minutes.
Answer: Using a bucket, the tank can be filled in 1 hour and 15 minutes.
