For this case we have that by definition the time is given by:


t=(d)/(v)

Where the variable "d" represents the distance and "v" represents the speed.

So, first we need to know the total distance:


d=(v)(t)


d=(60)(8)


d=480 mi

Then, the time for 75mph is given by:


t=(480)/(75)


t=6,4

6,4 hours
