To calculate average speed, you need the
following equation:
distance = average speed
time
Example
Distance: a lap was 300 metres long.
4 x 300 metres = 1,200 metres
Time: Adams completed the 1,200 metres
in 63 seconds
1,200 19.05 metres
So, average speed: 63 € per second (m/s)
To calculate average speed in kilometres
per hour, use this equation:
Average speed in metres per second (m/s)
x 3.6 = average speed in kilometres per hour
(km/h)​

Well, there are different kinds of conflicts: personal, political and global. I would like to tell you a few words about personal conflicts. These conflicts are happened between different people: between classmates, friends, students and teachers and of course, between the members of a family. Many of teenagers can't help relying on their parents because they dream to be independent and have enough pocket money.  But when I need some money I prefer to ask it from my parents because I have no time and opportunity to earn money. I must study hard to enter the institute. It is my job now. I think that the most common cause of conflicts is misunderstanding. To my mind to avoid any conflict we should be more tolerant to each other.
