Answer:
4.5 hours.
= 4 hours and 30 minutes.
Step-by-step explanation:
Distance = Rate x Time
in this case, D = 459 miles
because each driver will drive for the same length of time, we can use their average rate
so, D = average rate x Time
459 miles = (53mph + 49mph)/2 x Time
459 miles / 51mph = 9 hours
Since the total time is 9 hours, each driver will drive for 4 hours 30mins.
Proof: 53mph x 4.5h + 49mph x 4.5h
= 238.5m + 220.5m = 459 miles
