Answer:
[tex]\boxed {\boxed {\sf A.\ 30 \ mph \ north}}[/tex]
Step-by-step explanation:
Velocity can be found by dividing the displacement by the time.
[tex]v=\frac{s}{t}[/tex]
The displacement of the truck is 75 miles north. The time is 2.5 hours.
[tex]s= 75 \ miles \ north \\t= 2.5 \ hr[/tex]
Substitute the values into the formula.
[tex]v=\frac{75 \ miles \ north }{ 2.5 \ hr}[/tex]
Divide.
[tex]v= 30 \ miles \ north / hr[/tex]
[tex]v= 30 \ miles/hour \ north[/tex]
The velocity of the truck is 30 miles per hour north.
