Question

От вокзала отъехали одновременно в противоположных направлениях машина и автобус.скорость машины 120 км/ч,а скорость автобуса 80 км/ч. какое расстояние будет между ними через 2 часа?

Answer 1

120*2=240
80*2=160
160+240=400
або
120+80=200
200*2=400

Answer 2

S=V*t(путь =скорость *на время)
120*2=240
80*2=160
и потом слаживаешь пути. 160+240=400

Answer 3

Problem Analysis

We are given that a car and a bus start moving simultaneously in opposite directions from a train station. The car's speed is 120 km/h, and the bus's speed is 80 km/h. We need to find the distance between them after 2 hours.

Calculation

To find the distance between the car and the bus after 2 hours, we can use the formula:

Distance = Speed × Time

For the car, the distance it travels in 2 hours is: Distance_car = Speed_car × Time = 120 km/h × 2 h = 240 km.

For the bus, the distance it travels in 2 hours is: Distance_bus = Speed_bus × Time = 80 km/h × 2 h = 160 km.

Since the car and the bus are moving in opposite directions, the total distance between them is the sum of the distances traveled by each vehicle: Total_distance = Distance_car + Distance_bus = 240 km + 160 km = 400 km.

Therefore, the distance between the car and the bus after 2 hours is 400 kilometers.

Answer

The distance between the car and the bus after 2 hours is 400 kilometers.
