Question

Турист направляется из одного города в другой. Он проехал 2 ч на автомобиле со скоростью 70км/ч, потом 4 ч шёл пешком со скоростью 5км/ч, и после этого ему осталось пройти 14 км. Чему равно расстояние между городами?

Answer 1

Решение:
2*70=140 - км турист проехал;4*5=20 - турист прошел пешком
140+20+14=174 км расстояние между городами

Если нужно уравнением то:
x=2*70+4*5+14;
x=140+20+14;
x=174
Ответ: Расстояние между городами=174 км

Answer 2

70*2=140 км на автомобиле
5*4=20 км пешком
140+20+14=174 км весь путь

Answer 3

Calculation of the Distance Between Cities

To calculate the distance between the two cities, we need to add up the distances covered by the tourist in each mode of transportation.

1. Distance covered by car: The tourist traveled for 2 hours at a speed of 70 km/h. Therefore, the distance covered by car is 2 hours * 70 km/h = 140 km.

2. Distance covered on foot: The tourist walked for 4 hours at a speed of 5 km/h. Therefore, the distance covered on foot is 4 hours * 5 km/h = 20 km.

3. Remaining distance: After traveling by car and walking, the tourist still needs to cover 14 km to reach the destination.

To find the total distance between the cities, we add up the distances covered in each mode of transportation and the remaining distance:

Total distance = Distance covered by car + Distance covered on foot + Remaining distance

Total distance = 140 km + 20 km + 14 km = 174 km

Therefore, the distance between the two cities is 174 km.
