Respuesta :

Elena’s family is driving on the freeway at 55 miles per hour.

Therefore, the distance, d covered by Elena's family is:

[tex]d=55t[/tex]

When the input, t = 3 minutes

[tex]\begin{gathered} d=55\times\frac{3}{60} \\ =2.75\text{ miles} \end{gathered}[/tex]

Note: We divide by 60 to convert it to hours since their speed is given in miles per hour.

For Andre's family, when the input, t= 3 minutes

• Distance covered, d= 3 miles

Therefore, in 3 minutes, Elena's family will have covered 2.75 miles while Andre's family will cover 2.75 miles.
