Question

Из пунктов находящихся на расстоянии 130 километров друг от друга в одно и тоже время в противоположных направлениях выехали два автобуса скорость первого автобуса 65 километров в час а другого скорость на 10 километров меньше На каком расстоянии друг от друга не будет через 6 часов после начала движения

Answer 1

65+(65-10)=120 км/ч - общая скорость автобусов
120*6=720 км/ч - проедут за 6 часов
720+130=850 км - расстояние между автобусами через 6 часов

Answer 2

Problem Analysis

Two buses start from points that are 130 kilometers apart in opposite directions at the same time. The first bus has a speed of 65 kilometers per hour, while the second bus has a speed 10 kilometers per hour slower than the first bus. We need to determine the distance between the two buses after 6 hours.

Solution

To find the distance between the two buses after 6 hours, we can calculate the distance traveled by each bus and then find the difference between their distances.

Let's calculate the distance traveled by each bus after 6 hours.

The distance traveled by the first bus can be calculated using the formula: Distance = Speed × Time.

For the first bus: - Speed = 65 kilometers per hour - Time = 6 hours

Using the formula, we can calculate the distance traveled by the first bus after 6 hours.

For the second bus: - Speed = 65 - 10 = 55 kilometers per hour (since the second bus has a speed 10 kilometers per hour slower than the first bus) - Time = 6 hours

Using the formula, we can calculate the distance traveled by the second bus after 6 hours.

Finally, we can find the distance between the two buses by subtracting the distance traveled by the second bus from the distance traveled by the first bus.

Let's calculate the distances:

Calculation

Distance traveled by the first bus after 6 hours: Distance1 = Speed1 × Time = 65 km/h × 6 h = 390 km.

Distance traveled by the second bus after 6 hours: Distance2 = Speed2 × Time = 55 km/h × 6 h = 330 km.

Distance between the two buses after 6 hours: Distance between the buses = Distance1 - Distance2 = 390 km - 330 km = 60 km.

Answer

After 6 hours, the two buses will be 60 kilometers apart from each other.
