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?

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
