Answers:
a) Miami to Orlando: 57.14 mph
Orlando to Tampa: 48 mph
b) Entire trip: 54.74 mph
Step-by-step explanation:
The average speed can be calculated as the total distance traveled divided by the total time. So, the average speed of each part of the trip is
Miami to Orlando
Avg speed = 200 miles/3.5 h = 57.14 mph
Orlando to Tampa
Avg speed = 60 miles/1.25 h = 48 mph
Then, the average speed of the entire trip is
Avg speed = (200 mi + 60 mi)/(3.5 h + 1.25 h)
Avg speed = 54.74 mph
