Complete Question:
A finch rides on the back of a Galapagos tortoise, which walks
at the stately pace of 0.060 m/s. After 1.5 minutes the finch tires of
the tortoise’s slow pace, and takes flight in the same direction for
another 1.5 minutes at 11 m/s.
What was the average speed of the finch for this 3.0-minute interval?
Answer:

Step-by-step explanation:
Distance is calculated as:

First, we calculate the distance for the first 1.5 minutes
For the first 1.5 minutes, we have:



Convert 1.5 mins to seconds


Next, we calculate the distance for the next 1.5 minutes



Convert 1.5 mins to seconds


Total distance is:


The average speed for the 3.0 minute interval is:


Convert 3.0 minutes to seconds
