Respuesta :

ANSWER:

A. 337.5 miles

STEP-BY-STEP EXPLANATION:

What we must do is calculate the distance in each section, when the speed and time vary, the sum of both section is the total distance:

Section 1:

[tex]50\frac{\text{ miles}}{\text{ hours}}\cdot3.5\text{ hours}=175\text{ miles}[/tex]

Section 2:

[tex]65\frac{\text{ miles}}{\text{ hours}}\cdot2.5\text{hours}=162.5\text{ miles}[/tex]

The total distance is:

[tex]d=175+162.5=337.5\text{ miles}[/tex]
