Answer :
Answer:
v= 72 miles/hour
Explanation:
Speed
The speed is the ratio of the distance x traveled by an object and the time t it took to complete the distance.
We calculate the speed as follows:
[tex]\displaystyle v=\frac{x}{t}[/tex]
The truck was timed taking t=5 seconds between posts that are x=0.1 miles apart.
The speed of the truck is:
[tex]\displaystyle v=\frac{0.1}{5}[/tex]
[tex]v=0.02\ miles/sec[/tex]
Since 1 hour = 3,600 seconds:
v=0.02 * 3,600 miles/hour
v= 72 miles/hour
