Question

Из двух городов,расстояние между которыми 400 км,одновременно навстречу друг другу выехали легковой автомобиль и рейсовый автобус.Через какое время они встретятся,если скорость автомобиля 96 км/ч,а скорость автобуса составляет 2/3 скорости автомобиля? Решите задачку плиз) По действиям(желательно)Буду очень благодарна:3

Answer 1

96:3×2=64 (км/ч) - скорость автобуса
64+96=160 (км/ч) - скорость сближения
400:160=2,5 (ч)
Ответ: через 2 часа 30 мин они встретятся

Answer 2

Problem Analysis

We are given that a car and a bus start simultaneously from two cities that are 400 km apart and are moving towards each other. We need to find the time it takes for them to meet. The car's speed is given as 96 km/h, and the bus's speed is 2/3 of the car's speed.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it takes for the car and the bus to meet.

1. Calculate the speed of the bus: - The speed of the bus is given as 2/3 of the car's speed. - So, the speed of the bus is (2/3) * 96 km/h = 64 km/h.

2. Calculate the time it takes for the car and the bus to meet: - The total distance between the two cities is 400 km. - Since the car and the bus are moving towards each other, their combined speed is the sum of their individual speeds. - The combined speed of the car and the bus is 96 km/h + 64 km/h = 160 km/h. - Using the formula time = distance / speed, the time it takes for them to meet is 400 km / 160 km/h = 2.5 hours.

Therefore, the car and the bus will meet after 2.5 hours.

Answer

The car and the bus will meet after 2.5 hours.
