Two towns accumulated different amounts of snow. In town 1, the snow depth is increasing by 3 1/2 inches every hour. In town 2 the snow depth is increasing by 2 1/4 inches every hour. In how many hours will the snowfalls of the towns be equal?

Respuesta :

Solving algebraic word problems involve, defining the variables, from which an  equation is written and then solved

[tex]\underline{The \ time \ when \ the \ snowfall \ would \ be \ equal, \ t = \dfrac{4 \times (y - x)}{5}}[/tex]

Where;

y - x = The difference between the amount of snow accumulated in town 2 and the amount of snow accumulated in town 1 respectively

The reason the above expression for the time is correct is given as follows:

The given rate at which the snow depth is increasing are:

The snow depth is increasing by 3 1/2 inches every hour in town 1

The snow depth is increasing by 2 1/4 inches every hour in town 2

Required:

The time in hours at which the snowfalls of the towns will be equal

Solution:

Let x represent the accumulated  snow in town 1, and let y represent the accumulated snow in town 2, at the time, t, when the accumulated snow will be equal, we have;

[tex]x + 3\frac{1}{2} \times t = y + 2\frac{1}{4} \times t[/tex]

Which gives;

[tex]x + \dfrac{7 \cdot t}{2} = y + \dfrac{9 \cdot t}{4}[/tex]

Collecting like terms gives;

[tex]\dfrac{7 \cdot t}{2} -\dfrac{9 \cdot t}{4} = y - x[/tex]

[tex]The \ time \ when \ the \ snowfall \ would \ be \ equal, \ t = \mathbf{\dfrac{4 \times (y - x)}{5}}[/tex]

Where;

x = The accumulated snowfall in town 1

y = The accumulated snowfall in town 2
