Question

поезд прошёл 336 км за 4 часа автобус прошёл 126 км за 3 часа Во сколько раз скорость автобуса меньше скорости поезда? Решите пж с условием и решением .​

Answer 1

Ответ:в 2 раза

Пошаговое объяснение:

---- ---------- S --- t ---- V

Поезд -----------336км 4 часа ?

Автобус--------- 126км 3 часа ?

Обединяешь скобкой ставишь ? Пишешь во сколько

336÷4=84 км/час скорость поезда

126÷3=42 км/час скорость автобуса

84÷42=2

Answer 2

Problem Analysis

We are given that a train traveled 336 km in 4 hours, and a bus traveled 126 km in 3 hours. We need to determine the ratio of the bus's speed to the train's speed.

Solution

To find the ratio of the bus's speed to the train's speed, we can divide the distance traveled by the time taken for each mode of transportation.

Let's calculate the speeds of the train and the bus:

- Train speed = Distance traveled by the train / Time taken by the train = 336 km / 4 hours = 84 km/h. - Bus speed = Distance traveled by the bus / Time taken by the bus = 126 km / 3 hours = 42 km/h.

To find the ratio of the bus's speed to the train's speed, we divide the bus speed by the train speed:

Bus speed / Train speed = 42 km/h / 84 km/h = 0.5.

Therefore, the speed of the bus is 0.5 times (or half) the speed of the train.

Answer

The speed of the bus is 0.5 times (or half) the speed of the train.
