Answer:
51.35 mph to the nearest hundredth.
Step-by-step explanation:
The time she takes to travel 60 miles = distance / average speed
= 60/50 = 1.2 hours.
Total time taken = 1.2 + 2.5
= 3.7 hours.
Total distance travelled = 60 + 130
= 190 miles.
Therefore average speed for the whole journey
= 190 / 3.7
= 51.35135 mph.
