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

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
