A truck driver who covers the interstate in 4 1/2hours traveling at the posted speed of 55 mph. If the speed limit is raised to 65 mph, how much time will the same trip require

Respuesta :

Answer: The same trip will require 3.8 hours.

Step-by-step explanation:

Since we have given that

Time = [tex]4\dfrac{1}{2}=\dfrac{9}{2}[/tex]

Speed = 55 mph

So, distance would be

[tex]Speed\times time=55\times 4.5=247.5\ miles[/tex]

If the speed limit = 65 mph

So, time will be

[tex]\dfrac{247.5}{65}=3.8\ hours[/tex]

Hence, the same trip will require 3.8 hours.
