Distance Tameron has to travel to reach college = 540 miles
Average speed at which Tameron drives = 45 miles per hour
It is required to find the number of hours it will take Tameron to drive upto 3/4th of the total distance to college. For this purpose we have to first find the 3/4 of the total distance.
Then
3/4 of the total distance to college = (3/4) * 540
= 3 * 135
= 405 miles.
Then
The time taken by Tameron to drive 405 miles = Distance traveled/Speed
= 405/45
= 9 hours.
So it will take Tameron 9 hours to drive 3/4 of the total distance to college.
