A tap leaks at the rate of 2cm\(^3\) per seconds. How long will it take the tap to fill a container of 45 liters capacity? (1 liters = 1000cm\(^3\))
8 hours
6hr 15min
4hr 25min
3hr
Penjelasan
Total capacity of the container = 45 liters = 45 x 1000
= 45000 cm\(^3\)
Time to fill the container = \(\frac{45000}{2}\)
= 22500 seconds
= \(\frac{22500}{3600}\)
= 6 hr 15 mins
