Answer:

\frac{ {x}^{2} }{y(x - y)}  +  \frac{ {y}^{2} }{ - x(x - y)}

\frac{ {x}^{2} }{y(x - y)}  -  \frac{ {y}^{2} }{x(x - y)}

\frac{ {x}^{2}  \times x  -  {y}^{2}  \times y}{xy(x -y)}

\frac{(x - y)( {x}^{2}  + xy +  {y}^{2}) }{xy(x - y)}

\frac{ {x}^{2} + xy +  {y}^{2}  }{xy}

STatiana [176]

Answer:

2 hours

Step-by-step explanation:

you can write two linear equations and then set them equal to each other to see when they intersect. so for the first equation which will be representing the junior space cadets distance from his house. this can be written as

d = 50t + 50

where t represents time and d represents distance. there is 50 being added to the equation since he had already been traveling for an hour

the second equation which will represent his sister Gwen can be represented as

d = 75t

Now we set them equal to each other

50t + 50 = 75t

50 = 25t

2 = t
