Asmall submarine is at –1,320 feet in relation to sea level. the submarine needs to be at 180 feet below sea level in 60 minutes. another submarine is at –1,440 feet, and also needs to be at 180 feet below sea level in 60 minutes. how much faster does the second submarine need to travel? explain.

Sample Response: : The first submarine needs to travel at 19 feet per minute to rise to –180 feet. The second submarine needs to travel at 21 feet per minute to rise to –180 feet. The second submarine must travel 2 feet per minute faster than the first.

Step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
