Question

(ПОМОГИТЕ,НАПИШИТЕ ПОЖАЛУЙСТА С УСЛОВИЕМ) Реши задачу. До окончания посадки в поезд оставалось две минуты, когда автомобилист находился в 1 900 м от вокзала. Первую ми- нуту он ехал со скоростью 54 км/ч. Оставшееся расстояние он преодолел за 1 минуту. С какой скоростью он двигался? Вырази ответ в км/ч.

Answer 1

54*10/36=15 м/с
60*15=900м
1000/60=16,67
16.67*36=600
600/10= 60 км/ч
ответ 60 км/ч

Answer 2

Problem Analysis

To solve this problem, we need to determine the speed at which the driver was traveling when he covered the remaining distance in 1 minute. We are given that the driver was initially 1,900 meters away from the train station and had 2 minutes left until the end of the train's arrival. In the first minute, the driver traveled at a speed of 54 km/h. We need to find the speed at which the driver covered the remaining distance in the second minute.

Solution

To find the speed at which the driver covered the remaining distance, we can use the formula:

Speed = Distance / Time

Let's calculate the distance covered in the first minute: Distance1 = Speed1 * Time1 = 54 km/h * 1/60 h = 0.9 km

The remaining distance can be calculated as: Remaining Distance = Total Distance - Distance1 = 1.9 km - 0.9 km = 1 km

Now, we can calculate the speed at which the driver covered the remaining distance in the second minute: Speed2 = Remaining Distance / Time2 = 1 km / 1/60 h = 60 km/h

Therefore, the driver was traveling at a speed of 60 km/h when he covered the remaining distance in 1 minute.

Answer

The driver was traveling at a speed of 60 km/h when he covered the remaining distance in 1 minute.
