A hiker is walking down a straight road traveling due west. Her journey can be thought of as occurring in 3 consecutive parts: traveling 95 minutes at 0.75 m/s, 75 minutes at 1.1 m/s, and then 26 minutes at 0.92 m/s. A. What is her velocity for each part?

Esteban Marshall · Answer 1

Velocity in the first part = 0.75 m/s

Velocity in the second part = 1.1 m/s

Velocity in the third part = 0.92 m/s

Explanation:

Conceptual analysis : The velocity is defined by the following formula:

v = d/t

Where:

v : velocity in The speed in meters over second (m/s)

d : distance in meters (m)

t : time in seconds (s)

Problem development

velocity in the first part = 0.75 m/s

velocity in the second part = 1.1 m/s

velocity in the third part = 0.92 m/s
