Question

Помогите решить задачу-Автобус и такси одновременно вышли в противоположных направлениях. Скорость такси 120км.ч а скорость автобуса в 3 раза меньше. через сколько часов расстояние между ними будет 1120?

Answer 1

Скорость автобуса равна 120:3=40 км/ч. За 1 час они вместе преодолеют путь 120+40=160 км. 1120:160=7 часов. Ответ: через 7 часов между ними будет расстояние 1120 км

Answer 2

Сначала находим скорость автобуса,120:3=40(км/ч)
дальше узнаем общую скорость,120+40=160,затем делим 1120:160=7(ч)через 7 часов или встретятся)) :)

Answer 3

Solving the Problem of the Bus and Taxi

To solve the problem of the bus and taxi traveling in opposite directions, we can use the formula:

Distance = Speed × Time

Given that the speed of the taxi is 120 km/h and the speed of the bus is 3 times less, we can represent the speed of the bus as 120/3 = 40 km/h.

Let's denote the time it takes for the distance between them to be 1120 km as t hours.

Calculating the Time

We can use the formula Distance = Speed × Time for both the taxi and the bus:

For the taxi: Distance = 120t (since the speed of the taxi is 120 km/h)

For the bus: Distance = 40t (since the speed of the bus is 40 km/h)

Setting up the equation: 120t + 40t = 1120

Solving for t: 160t = 1120 t = 1120 / 160 t = 7

So, it will take 7 hours for the distance between the bus and the taxi to be 1120 km.

Final Answer

After solving the equation, we find that it will take 7 hours for the distance between the bus and the taxi to be 1120 km.
