Answer 1

Расстояние-4 км=4000 м
Скорость-80 м/мин
Сколько останется пройти ч/з 30 мин-?
За какое врямя пройдет оставшийся путь-? мин

1)80х30=2400 м- прошел за 30 мин
2)4000-2400=1600 м- останется пройти
3)1600:80=20 мин- оставшийся путь пройдет за 20 мин
Ответ: 1600 м; за 20 мин

Answer 2

 1600 м останется пройти ; 20 минут он будет идти оставшееся расстояние.

Answer 3

Calculation of Remaining Distance and Time Required

To calculate the remaining distance that Vanya needs to cover and the time required to cover that distance, we can use the given information.

Given: - Distance from the village to the station: 4 km - Vanya's walking speed: 80 m/min

To find the remaining distance after half an hour, we need to calculate the distance Vanya has already covered in that time.

Step 1: Convert the given walking speed from meters per minute to kilometers per minute. - Vanya's walking speed: 80 m/min - Conversion factor: 1 km = 1000 m - Conversion: 80 m/min * (1 km / 1000 m) = 0.08 km/min

Step 2: Calculate the distance covered by Vanya in half an hour. - Time: 30 minutes - Distance covered: Speed * Time = 0.08 km/min * 30 min = 2.4 km

Step 3: Calculate the remaining distance. - Total distance: 4 km - Distance covered: 2.4 km - Remaining distance: Total distance - Distance covered = 4 km - 2.4 km = 1.6 km

Therefore, Vanya has 1.6 km left to cover.

Step 4: Calculate the time required to cover the remaining distance. - Remaining distance: 1.6 km - Walking speed: 0.08 km/min - Time required: Remaining distance / Walking speed = 1.6 km / 0.08 km/min = 20 minutes

Therefore, Vanya will require 20 minutes to cover the remaining distance.

Answer

Vanya has 1.6 km left to cover after half an hour, and it will take him 20 minutes to cover the remaining distance.
