Giant Snake (MonsterVerse) KE

The Giant Snake is like a pit viper, and is 60 ft. 
Assuming this: a pit viper is 3-5 kg, average is then 4. 
To get from 30 cm (pit viper size) to 18 meters (as I assume 1 ft is 0.3 meters) is multiply by 60. 
So 4x60 is 240 kg. 
Assuming the same for speed. 
160 m/s x 60 is 9600 m/s
