Question

A tap fills a 500-cm³ beaker at a rate of 20 cm³ in 1 second. At this rate, how long does it take to fill the beaker to the brim?

Option 1: 25 seconds
Option 2: 20 seconds
Option 3: 15 seconds
Option 4: 30 seconds

Answer 1

To determine the time it takes to fill a beaker at a given rate, divide the total volume of the beaker by the filling rate. A beaker with a volume of 500 cm³ filled at a rate of 20 cm³/s will take 25 seconds to fill.

Step-by-step explanation:

The question relates to a rate problem in mathematics where we need to calculate the time taken to fill a container at a given rate. To solve this, we can use the formula time = total volume/rate. Given that, a tap fills a beaker at a rate of 20 cm³/s and the beaker's total volume is 500 cm³, we can plug these values into the formula:

time = 500 cm³ / 20 cm³/s = 25 seconds.

Therefore, it takes 25 seconds to fill the beaker to the brim.
