Question

Помогите решить задачу. Из одного населённого 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 опередил первый автобус на 40 км. С какой скоростью он двигался? Срочно. ​

Answer 1

Ответ: ну получаеться 85, если 40км за 2 часа, тогда в час 1 автобус отставал на 20км ,40/2=20, 65кмч+20кмч=85км ч- скорость 2 автобуса

Problem Analysis

We are given that two buses start simultaneously from a point, with the first bus traveling at a speed of 65 km/h. The second bus, which is faster, overtakes the first bus after 2 hours and is ahead by 40 km. We need to determine the speed of the second bus.

Solution

Let's assume the speed of the second bus is x km/h.

After 2 hours, the first bus has traveled a distance of 65 km/h * 2 h = 130 km.

At this point, the second bus overtakes the first bus and is ahead by 40 km. Therefore, the second bus has traveled a distance of 130 km + 40 km = 170 km.

Since the time taken by both buses is the same, we can set up the following equation:

Distance traveled by the first bus = Distance traveled by the second bus

130 km = 170 km

Now, we can solve for the speed of the second bus:

x km/h = (170 km - 130 km) / 2 h

Simplifying the equation:

x km/h = 40 km / 2 h

x km/h = 20 km/h

Therefore, the speed of the second bus is 20 km/h.

Answer

The second bus was traveling at a speed of 20 km/h.
