The mathematician explains why he does not compensate to overcome 120 km/h on the highway to arrive before arriving before

Many believe that overcoming the permissible speed limit on highways is a good idea to get to the destination earlier for a simple reason: the faster, the less it is required to make the route. In a sense, yes, if the speeds are achieved much more than the permitted 120 km/h on motorways. But, according to the teacher of mathematics, An increase of 20 km/h more, made by some drivers To achieve already prohibited 140 km/h, it is useless.

In Spain, remember, the maximum speed with which the driver can go along the highway is 120 km/h, But many miss this standard for several reasons: some believe that you can increase this permitted speed to advance, and that it does not carry any sanctions to be only a few more numbers. Others, however, simply prefer to achieve greater speed, even according to customs, even if it does not compensate at all.

In the video posted on Tiktok, in order to increase awareness among drivers, the mathematician Jose Angel Murcia showed how he does not compensate for overcome the limit of the highway, because even this will not be able to get to the destination ahead of schedule. In fact, if you decide to move from 120 km/ha 140, You will restore only a few seconds for each kilometer.

Overcome 120 km/h on the highway does not serve

In the video, the mathematician, according to the visible, performs simple calculations on the board. It begins with the statement that at a speed of 60 km/h on the highway they obviously pass 60 kilometers per hour, which, in turn, is a kilometer every 60 seconds. If the driver folds speed and passes up to 120 km/h, It will take exactly half to make the same 60 kilometerSince this is twice as much initial speed.

Now that the driver moves from 120 km/ha 140 on the highway, the speed does not fold, but simply increases it slightly. If we continue with the same rule, go through a kilometer at a speed of 140 km/h A few less than 26 secondsThe field, that is, we barely win 4 seconds for each kilometer.

This is because Speed ​​and time have feedbackThe field, that is, obviously, the faster, the faster you go, but this saving of time gradually decreases as speed increases. Therefore, there is no significant leap in time, who won, as it might seem.

In addition, we must take into account the risks that lead to more than 120 km/h on the highway or on any other road. Overcoming the speed restriction entails a fine of 100 euros without loss of points, but if the speed reaches 151 to 170 km/h, this is a fine of 300 euros and the loss of two points. At speeds more than 190, The sanction is 600 euros and the loss of points in total 6In addition, the risk of accident is much higher.
