Answer:yes, you will make the journey on time.
Step-by-step explanation:
The distance between San Antonio and Dallas is 277 miles.
Distance covered = speed/time
Time = distance covered/speed of the car.
If you drive at a flat rate of 65 miles per hour, it means that the time it will take you to cover 277 miles will be
277/65 = 4 17/65 = 4.26 hours
The amount of time that you have for the journey is 4 1/2 hours = 4.5 hours. Since 4.5 hours is greater than 4.26 hours, then you will make the journey on time.
