Question

От стадиона до библиотеки на трамвае можно доехать за 30 минут а на такси до 12 минут через сколько минут произойдёт встреча если выехали одновременно навстречу друг другу на трамвае на такси от стадиона до библиотеки

Answer 1

Примем путь за 1.
1 : 12 = 1/12 - расстояния можно проехать за 1 минуту на такси.
1 : 30 = 1/30 - расстояния можно проехать за 1 минуту на трамвае.
1/12 + 1/30 = 5/60 + 2/60 = 7/60 - расстояния проезжают совместно за 1 минуту трамвай и такси.
1 : 7 * 60 = 60/7 = 8 4/7 (мин) - время, через которое произойдет встреча.
Ответ: 8 4/7 мин.

Answer 2

Calculation of Meeting Time

To calculate the meeting time between the tram and the taxi, we need to determine the time it takes for each mode of transportation to travel from the stadium to the library.

According to the information provided, the tram takes 30 minutes to travel from the stadium to the library, while the taxi takes 12 minutes for the same distance.

If both the tram and the taxi depart simultaneously from the stadium towards the library, we can calculate the meeting time by finding the least common multiple (LCM) of the two travel times.

The LCM of 30 minutes and 12 minutes is 60 minutes. Therefore, the tram and the taxi will meet after 60 minutes.

Answer: The tram and the taxi will meet after 60 minutes.
