The elevation of our concerned submarine will change by (-11/2) miles after 15 explorations, if the elevation changes by (-3/8) miles after one exploration, solved using linear equation.
As per the question statement, the elevation of a submarine changes by (-3/8) miles after each exploration.
We are required to calculate the number of explorations after which the elevation of our concerned submarine will change by (-11/2) miles.
Let us assume that, the elevation of our concerned submarine will change by (-11/2) miles after "x" explorations. We will now require to form a linear equation of single variable (x), based on the condition mentioned in the question statement, and solving for "x", we will obtain our required answer.
That is, [{(-3/8)*x} = (-11/2)]
or, x = [(-11/2)/{(-3/8)]
or, x = 14.66
or, x = 15 (approximated, since number of exploration cannot be a decimal).
- Linear Equation: In Mathematics, a Linear Equation an equation of degree 1, which when plotted, gives a straight line.
