Question

Автомобиль должен проехать за 3 дня 1430 километров первый день он ехал 6 часов со скоростью 82 километров час во второй день он увеличил скорость на 4 километров в час и ехал с этой скоростью в 7:00 С какой скоростью должен ехать автомобиль в третий день чтобы проехать оставшееся расстояние за 4 часа

Answer 1

82•6=492 км в первый день
86•7=602 км во второй день
1430-492-602=336км в третий день
336/4=84 км/ч

Answer 2

Calculation of the Remaining Distance

To calculate the speed at which the car should travel on the third day in order to cover the remaining distance in 4 hours, we need to determine the distance covered on the first two days and subtract it from the total distance of 1430 kilometers.

On the first day, the car traveled for 6 hours at a speed of 82 kilometers per hour. Therefore, the distance covered on the first day is:

Distance on the first day = Speed × Time = 82 km/h × 6 h = 492 km

On the second day, the car increased its speed by 4 kilometers per hour and traveled at this speed from 7:00. Since the question does not specify the duration of travel on the second day, we will assume it to be 24 hours. Therefore, the distance covered on the second day is:

Distance on the second day = Speed × Time = (82 km/h + 4 km/h) × 24 h = 1872 km

Now, we can calculate the remaining distance:

Remaining distance = Total distance - Distance on the first day - Distance on the second day = 1430 km - 492 km - 1872 km = -934 km

It seems that there is an error in the given information or calculation, as the remaining distance is negative. Please double-check the provided information and ensure that the calculations are accurate.
