Which equation models the following word problem?Isabella and Mason competed in a long distance bike race. Isabella rode 5mph faster than Mason did. It took Mason 4 hours, where it took Isabella3 hours. How fast was each of them riding?

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
