Question

Реши задачу. из одного населенного пункта одновременно в одном направлении выехали два автобуса первый автобус двигался со скоростью 65 км ч а второй автобус двигался быстрее и через 2 часа Определи первый автобус на 40 км с какой скоростью он двигался​

Answer 1

Ответ:1) 65 * 2 = 130 (км) - проехал первый автобус; 2) 130 + 40 = 170 (км) - проехал второй автобус; Чтобы узнать с какой скоростью ехал второй автобус нужно расстояние, которое он проехал, разделить на время: 3) 170 : 2 = 85 (км/ч).

Answer 3

Problem Analysis

We have two buses that start from the same location and travel in the same direction. The first bus travels at a speed of 65 km/h, while the second bus is faster. After 2 hours, the first bus is 40 km ahead of the second bus. We need to determine the speed at which the first bus is traveling.

Solution

Let's assume the speed of the second bus is x km/h. Since the first bus is 40 km ahead of the second bus after 2 hours, we can calculate the distance traveled by each bus.

The distance traveled by the first bus is given by: Distance = Speed × Time Distance = 65 km/h × 2 h = 130 km

The distance traveled by the second bus is given by: Distance = Speed × Time Distance = x km/h × 2 h = 2x km

Since the first bus is 40 km ahead of the second bus, we can set up the following equation: 130 km = 2x km + 40 km

Simplifying the equation, we get: 2x km = 130 km - 40 km 2x km = 90 km

Dividing both sides of the equation by 2, we find: x km = 90 km / 2 x km = 45 km/h

Therefore, the speed of the first bus is 45 km/h.

Answer

The first bus was traveling at a speed of 45 km/h.
