Question

реши задачку.от автобусной станции в противоположном направлении одновременно отошли два автобуса. первый автобус шёл со скоростью 60 км / ч и был в пути 2 ч. второй автобу за это время проехал на 20 км больше,чем первый. с какой скоростью ехал второй автобус?чему равно расстояние между автобусами?не спамте,пожалуйста!долго очень печатала!

Answer 1

1)60*2=120(км)проехал1 автобус за2часа.                                                                                               2)120+20=140(км)проехал2 автобус.                                                                                                          3)140:2=70(км/ч)скорость2 автобуса.                                                                                                        4)140+120=260(км)расстояние между автобусами.                                                                              Ответ:70км/ч;260км. 

Answer 2

1)Сколько км проехал первый  автобус за 2 часа?

60*2=120(км)

2)Сколько км проехал второй автобус?

120+20=140(км)

3)С какой скоростью ехал второй автобус?

140/2=70(км/ч)

Answer 3

Problem Analysis

We are given two buses that start from a bus station in opposite directions. The first bus travels at a speed of 60 km/h and is on the road for 2 hours. The second bus travels a distance that is 20 km longer 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 assume the speed of the second bus is x km/h.

To find the speed of the second bus, we can set up the following equation based on the given information:

Distance traveled by the first bus = Distance traveled by the second bus + 20 km

Using the formula Distance = Speed × Time, we can write the equation as:

60 km/h × 2 hours = x km/h × 2 hours + 20 km

Simplifying the equation, we get:

120 km = 2x km + 20 km

Subtracting 20 km from both sides, we have:

100 km = 2x km

Dividing both sides by 2, we get:

50 km = x km

Therefore, the speed of the second bus is 50 km/h.

To find the distance between the two buses, we can use the formula Distance = Speed × Time with the speed of the first bus (60 km/h) and the time it traveled (2 hours):

Distance between the two buses = Speed of the first bus × Time traveled by the first bus

Distance between the two buses = 60 km/h × 2 hours

Simplifying the equation, we get:

Distance between the two buses = 120 km

Therefore, the distance between the two buses is 120 km.

Answer

The second bus was traveling at a speed of 50 km/h and the distance between the two buses was 120 km.
