Question

Из двух городов, расстояние между которыми 760 км, навстречу друг другу выехали автомобиль и автобус и встретились через 5 часов. Найдите скорость автобуса, если скорость автомобиля 85 км/ч.​

Answer 1

если они выехали одновременно. то до встречи шли 5 часов, тогда расстояние, которое прошел автомобиль, равно 85*5=425/км/. а оставшиеся 335 км (760-425=335) автобус ехал 5 часов, поэтому его скорость равна 335/5=67/км/ч/

Answer 2

Problem Analysis

We are given that the distance between two cities is 760 km. An automobile and a bus start from their respective cities and meet each other after 5 hours. We need to find the speed of the bus, given that the speed of the automobile is 85 km/h.

Solution

To find the speed of the bus, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the bus using this formula.

Calculation

The distance between the two cities is 760 km. The time taken to meet is 5 hours. The speed of the automobile is 85 km/h.

Using the formula, we can calculate the speed of the bus as follows:

Speed of the bus = Distance / Time

Speed of the bus = 760 km / 5 hours

Speed of the bus = 152 km/h

Therefore, the speed of the bus is 152 km/h.

Answer

The speed of the bus is 152 km/h.
