This is most often the format taken from the polynomial form of this problem, which is x^2-7x+12, and when it is in this format you just take each set of numbers within each parenthesis and set it to zero, then solve. In this case, x can be equal to either 3 or 4.

The Sognefjord is the deepest fjord in Norway at 1,308 metres (4,291 ft) If a submersible floating on the surface was to dive ve

natali 33 [55]

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is $1308-48=1260\ \text{m}$

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

$\dfrac{1263}{35}=36\ \text{minutes}$

The time taken by the submersible to dive the required distance is 36 minutes.
