Question

Расстояние между городами 336 км. Из них одновременно навстречу друг другу выехали 2 мотоцикла. Скорость одного мотоцикла 54 км/ч другого 58 км/ч. Через сколько часов мотоциклисты встретятся

Answer 1

1) 54 + 58 =112 (км/ч) - общая скорость
2) 336 ÷ 112 = 3 (ч) - до их встречи
Ответ : 3 часа

Answer 2

Problem Analysis

We are given that two motorcycles start simultaneously from two different cities and are traveling towards each other. The distance between the cities is 336 km. The speeds of the motorcycles are 54 km/h and 58 km/h. We need to determine how many hours it will take for the motorcycles to meet.

Calculation

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

Let's calculate the time it will take for each motorcycle to travel the given distance:

- Motorcycle 1: Speed = 54 km/h, Distance = 336 km - Time taken by Motorcycle 1 = 336 km / 54 km/h = 6.22 hours (rounded to two decimal places)

- Motorcycle 2: Speed = 58 km/h, Distance = 336 km - Time taken by Motorcycle 2 = 336 km / 58 km/h = 5.79 hours (rounded to two decimal places)

Since both motorcycles started simultaneously, they will meet when their total travel time is equal. Therefore, the motorcycles will meet after approximately 5.79 hours.

Answer

The motorcycles will meet after approximately 5.79 hours.
