Answer:

The travel time of the trip is 8.55 hours

Step-by-step explanation:

The average speed of an object is calculated using the following formula:

[tex]s=\frac{d_2 -d_1}{t}[/tex]

Where [tex]d_2 - d_1[/tex] is the total distance traveled by the object and t is the time it took the object to travel that distance.

So we know that:

[tex]d_2 - d_1=342\ miles[/tex]

[tex]s=40\ mph[/tex]

Therefore:

[tex]40=\frac{342}{t}[/tex]

[tex]t=\frac{342}{40}[/tex]

[tex]t=8.55\ hours[/tex]
