Question

От автобусной станции в противоположном направлении одновременно отошли два автобуса. Первый автобус шёл со скоростью 60 км/ч и был в пути 2 часа. Второй автобус за это время проехал на 20 км больше, чем первый. С какой скоростью ехал второй автобус? Чему равно расстояние между автобусами?

Answer 1

1)60х2=120 км. -прошел первый автобус за 2 ч. 2) 120+20=140 км. -прошел второй автобус за 2 ч. 3) 140:2=70 км/ч. - скорость второго автобуса. 4) 120+140=260км -расстояние

Answer 2

1) первый автобус прошёл 60 * 2= 120км
2) второй автобус прошёл на 20 км больше 120+20=140 км
3)140:2= 70 км/ч - скорость второго автобуса
4)120+140= 260 км расстояние между автобусами

Answer 3

Problem Analysis

We are given two buses that start simultaneously from an opposite direction. The first bus travels at a speed of 60 km/h and is on the road for 2 hours. The second bus travels 20 km more than the first bus in the same amount of time. We need to find the speed of the second bus and the distance between the two buses.

Solution

Let's start by finding the speed of the second bus.

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

The first bus travels at a speed of 60 km/h for 2 hours, so the distance covered by the first bus is:

Distance of the first bus = Speed of the first bus × Time = 60 km/h × 2 hours = 120 km.

The second bus travels 20 km more than the first bus in the same amount of time, so the distance covered by the second bus is:

Distance of the second bus = Distance of the first bus + 20 km = 120 km + 20 km = 140 km.

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

Distance of the second bus = Speed of the second bus × Time.

Substituting the values we found:

140 km = x km/h × 2 hours.

Simplifying the equation:

x km/h = 140 km / 2 hours = 70 km/h.

Therefore, the speed of the second bus is 70 km/h.

Now let's find the distance between the two buses.

The distance between the two buses is the difference in the distances covered by the two buses:

Distance between the buses = Distance of the second bus - Distance of the first bus = 140 km - 120 km = 20 km.

Therefore, the distance between the two buses is 20 km.

Answer

The second bus was traveling at a speed of 70 km/h. The distance between the two buses is 20 km.
