Final answer:
To find Michael's total driving time from Orlando to Savannah, sum the driving times from Orlando to Jacksonville (7.56 hours) and Jacksonville to Savannah (6.34 hours), which equals 13.9 hours.
Step-by-step explanation:
Michael's total driving time from Orlando to Savannah can be determined simply by adding the time he took to drive from Orlando to Jacksonville (7.56 hours) and the time from Jacksonville to Savannah (6.34 hours). To find the total driving time, you add these two amounts together:
- Orlando to Jacksonville = 7.56 hours
- Jacksonville to Savannah = 6.34 hours
By summing these times, we get:
Total driving time = 7.56 hours + 6.34 hours
Total driving time = 13.9 hours
Therefore, the correct answer is (a) 13.9 hours.
