Question

2) машина ехала со скоростью 120 км/ч. около поста дпс она сбросила скорость на 25 %. с какой скоростью проехала машина мимо поста дпс?

Answer 1

Calculation of the Speed of the Car

To calculate the speed at which the car passed the traffic police post, we need to consider that the car initially traveled at a speed of 120 km/h and then reduced its speed by 25%.

To find the new speed, we can calculate 25% of 120 km/h and subtract it from the initial speed.

Let's perform the calculation:

25% of 120 km/h = (25/100) * 120 km/h = 30 km/h

Therefore, the car reduced its speed by 30 km/h.

To find the speed at which the car passed the traffic police post, we subtract the reduced speed from the initial speed:

120 km/h - 30 km/h = 90 km/h

Therefore, the car passed the traffic police post at a speed of 90 km/h.

Please note that the calculation assumes a linear reduction in speed and does not take into account other factors that may affect the actual speed of the car.
