a. At what speed was Brandon flying?
b. What was his velocity?
2. Use the graph to answer the questions.

Answers

Answer 1
Answer:

Answer:

a. Bradon was flying at the speed rate of 350 miles/hour.

b. His velocity is 350 miles/hour due west.

Explanation:

The speed of an object is the ratio of distance moved to the time taken, while velocity is the ratio of displacement to time taken. The major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.

Vector quantities are described by both magnitude and direction, while scalar have only magnitude.

From the question,

distance = 700 miles and time taken = 2 hours

a. speed = (distance)/(time)

              = (700)/(2)

              = 350 miles/hour

∴     Bradon was flying at the speed rate of 350 miles/hour.

b. velocity = (displacement)/(time)

displacement = 700 miles of west, time taken = 2 hours

velocity = (700)/(2)

            = 350 miles/hour due west

His velocity is 350 miles/hour due west.
