Question

А. 7 Реши задачи.а) С автостанции одновременно отошли в противоположныхнаправлениях автобус и такси. Скорость такси — 90 км/час,а скорость автобуса — в 2 раза меньше. Через сколько часоврасстояние между ними составит 540 км?6) Из гаража одновременно в одном направлении вышли двеавтомашины. Одна шла со скоростью 80 км/час, а другая —со скоростью 65 км/час. На каком расстоянии друг от другабудут эти машины через 3 часа? ВНИМАНИЕ! МНЕ НУЖНО УСЛОВИЕ!! ЗАДАЧИ​

Answer 1

а)

Такси-90 км/ч

Автобус-? км/ч, в 2 раз <

Время-?ч

Расстояние-540 км

540:(90:2+90)=4 (ч)

б)

l-80 км/ч

ll-65 км/ч

t-3ч

s-? км

(80-65)•3=45 (км)

Answer 3

Problem 7a: Distance between a taxi and a bus

We are given that a taxi and a bus start from a bus station and travel in opposite directions. The speed of the taxi is 90 km/h, while the speed of the bus is half that of the taxi.

We need to find the time it takes for the distance between them to reach 540 km.

To solve this problem, we can use the formula:

Distance = Speed x Time

Let's assume that the time it takes for the distance between them to reach 540 km is t hours.

The distance traveled by the taxi in t hours is given by:

Distance traveled by taxi = Speed of taxi x Time = 90 km/h x t

The distance traveled by the bus in t hours is given by:

Distance traveled by bus = Speed of bus x Time = (90 km/h) / 2 x t

Since the taxi and the bus are traveling in opposite directions, the total distance between them is the sum of the distances traveled by each:

Total distance = Distance traveled by taxi + Distance traveled by bus

Substituting the values we have:

540 km = (90 km/h x t) + ((90 km/h) / 2 x t)

Simplifying the equation:

540 km = 90 km/h x t + 45 km/h x t

Combining like terms:

540 km = 135 km/h x t

Now, we can solve for t by dividing both sides of the equation by 135 km/h:

t = 540 km / 135 km/h = 4 hours

Therefore, it will take 4 hours for the distance between the taxi and the bus to reach 540 km.
