Answer:
Tia is planning a road trip and wants to estimate the total distance she will travel. She knows that the distance from her home to the first destination is 75.6 miles, and the distance from the first destination to the second destination is 42.3 miles. If she plans to continue her journey to a third destination located 18.9 miles away from the second destination, what is her estimated total travel distance?
Solution: In order to estimate the total travel distance, you'll simply need to add the distances together.
75.6+42.3+18.9=136.8 miles
Therefore, Tia's estimated total travel distance is approximately 136.8 miles.
