Answer 1

Answer:

10.42 km/hr

Step-by-step explanation:

jahaj ko dubne se bachane ke liye 60 litre pani paryapt

Ek pump Dwara 12 litre Pani bahar nikal Diya jata hai

=> 60 + 12  = 72 Litre pani ched se andar aana chaiye

6 minute Mein 15/8 litre Pani andar Aata Hai

15/8 litre Pani andar Aata Hai  -  6 Mins

1 Litre pani andar jata hai   - 6/(15/8)  = 16/5 min

72 Litre pani andar jayega = 72 *  16/5   = 1152/5  min mein

= 1152/300  hr

40 kilometre ki Duri

Speed  =  40 /(1152/300)  =  12000/1152  km/hr

= 10.42 km/hr
