Respuesta :

[tex](x)(4)+(x+5)(3)=Total\: distance[/tex]

1) The first thing to consider when tackling this question is that we are dealing with speed. And speed can be found this way:

[tex]speed=\frac{distance}{time}\Leftrightarrow d=st[/tex]

2) So, we can set our equation by calling x the distance. Since Mason took 4 hours and Isabella 3, we can start out writing:

[tex]\begin{gathered} dt_m+dt_I=Total\: distance \\ (x)t_M+(x+5)t_I=Total\: distance \\ (x)(4)+(x+5)(3)=Total\: distance \end{gathered}[/tex]

Note that the
