A car travels 480 km in 12 hr. what is its velocity

Explanation:

velocity=s/t

given distance is 480 km we have to convert it into meter because the unit of distance is meter

1 km=1000 m

480 km=480000 m =4.8*10^5

1 hour= 3600 s

12 hour =43200 s  

now velocity=s/t

v=4.8*10^5/43200

v=11.11 m/s

explanation:

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
