With the information given, it's not possible to calculate what it is now. But during that 90 minutes, its average velocity was 50 kph north.
The mean value is the total amount of petrol currently held in all the cars in the entire world, divided by the total number of cars. Good luck with that calculation. The median value would be almost impossible to calculate. The modal value, however, can probably be approximated. We must firstly assume the average amount of fuel in the tank to be just over half the average size of a fuel tank (since most people will refuel prior to the tank being completely empty and fill right to the top). Given that a common mid-sized saloon/hatchback fuel tank is around 60L (15gal), one might estimate that the modal amount of fuel in all cars is therefore approximately 35L.
Grand total
Newton's Second Law; A body of mass m subject to a net force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.To answer your question simply:Newton's second law of motion. The force the bumper car is subject to is proportional to its decelaration, (i.e the speed at which it comes to a stop)

a town has hight schools with 4,000 students each. What is the order of magnitude of the total number of high school students in the town?
Look distance is the total length covered by a body and displacement is the shortest length covered by a body. Also displacement is a vector quantity (has both magnitude and direction) and distance is a scalar quantity (has only magnitude and no direction)

A professional football team averaged 50,000 fans for each of its eight home games. What is the order of magnitude of the total attendance?
.56 times of total height
Blue jays average from eleven to twelve inches in total length.
No. The average speed is the average of the magnitude of the velocity but not the magnitude of the average of the velocity.This is because for vectors |A + B| ≤ |A| + |B|.Suppose you travel 100 metres due East at 10 metres per second and then 100 metres due North also at 10 metres per second. Your speed, throughout, is 10 metres per second and so that is your average speed.But your average velocity is the total displacement vector divided by the total time. This is100*sqrt(2) metres due NE/20 sec = 7.07 metres per second due North East.Its magnitude is 7.07 metres/sec.
I would prefer to use "distance" instead of "length".distance = speed x time
