Question

A tap leaks at the rate of 2cm³ per second.How long will it take the tap to fill a container of 45litres capacity.

Answer 1

Answer:

6 hours 15 minutes

Step-by-step explanation:

1 litre = 1000cm³

45 litres = 45000cm³

Volume = rate × time

45000 = 2 × t

t = 22500 secs

= 375 mins

Answer 2

Answers:

• 22500 seconds
• 375 minutes
• 6.25 hours
• 6 hours, 15 minutes

All time values listed above are equivalent, so you only need to pick one value to write as the answer.

======================================================

Work Shown:

1 liter = 1000 cubic cm

45 liters = 45*1000 = 45000 cubic cm

The container has a capacity of 45000 cubic cm

It will take 45000/2 = 22500 seconds to fill the container since the rate is 2 cubic cm per second.

-----------------

Convert from seconds to minutes

22500 seconds = (22500)*(1 min/60 sec)

22500 seconds = (22500/60) min

22500 seconds = 375 min

-----------------

Convert to hours

375 min = (375)*(1 hr/60 min)

375 min = (375/60) hr

375 min = 6.25 hr

----------------

Converting to hours,minutes

6.25 hr = 6 hr + 0.25 hr

6.25 hr = 6 hr + (0.25*60) min

6.25 hr = 6 hr + 15 min

6.25 hr = 6 hr, 15 min
