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

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

the answer is b
