Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
The water pressure of a sink has a steady flow of 2 cups per 10 minutes for the first 30 minutes. It still flows at 2 cups per 10 minutes for the next 30 minutes after. For the next hour, the water pressure maximizes to 4 cups per 10 minutes and stops. Shawn now has to dump half of the water away. How much water is left?

### Response:
 Kwa dakika za kwanza 30, vikombe 3*2=<<3*2=6>>6 vya maji vilitoka.
Kwa dakika zingine 30, vikombe 3*2=<<3*2=6>>6 vya maji vilitoka.
Kwa saa inayofuata, vikombe 6*4=<<6*4=24>>24 vya maji vilitoka.
24+6+6= <<24+6+6=36>>36 vikombe vya maji vilitoka.
Shawn alilazimika kumwaga maji ambayo yalisalia 36/2=<<36/2=18>>18 vikombe vya maji.
