Question

Автобус выехал из города N в 7:15 часов и прибыл в пункт назначения в 15:00. За время пути пути автобус делал три остановки по 15 минут. Чему равно расстояние между городами,если скорость автобуса 80 км/ч?

Answer 1

РЕШЕНИЕ
Вычисляем время в пути.
1)  15:00 - 07:15 = (14-7) : (60-15) = 07:45 - всё время на трассе.
2) 07:45 - 00:30 = 07:15 = 7ч 15 мин = 7 1/4 = 7.25 ч - время движения.
3) S = V*t = 80 * 7.25 = 580 км - расстояние - ОТВЕТ 

Answer 2

Calculation of Distance between Cities

To calculate the distance between the starting city (N) and the destination city, we need to consider the time taken by the bus, the speed of the bus, and the duration of the stops.

Given information: - The bus departed from city N at 7:15. - The bus arrived at the destination at 15:00. - The bus made three stops, each lasting 15 minutes. - The speed of the bus is 80 km/h.

To calculate the distance, we can use the formula:

Distance = Speed × Time

Let's break down the calculation step by step.

1. Calculate the total time taken by the bus: - The bus departed at 7:15 and arrived at 15:00, which means the total time taken is 7 hours and 45 minutes. - Convert the time to hours: 7 hours + 45 minutes / 60 minutes = 7.75 hours.

2. Calculate the time spent on stops: - The bus made three stops, each lasting 15 minutes. - Total time spent on stops = 3 stops × 15 minutes = 45 minutes. - Convert the time to hours: 45 minutes / 60 minutes = 0.75 hours.

3. Calculate the effective travel time: - Subtract the time spent on stops from the total time taken by the bus. - Effective travel time = Total time taken - Time spent on stops = 7.75 hours - 0.75 hours = 7 hours.

4. Calculate the distance: - Distance = Speed × Time = 80 km/h × 7 hours = 560 km.

Therefore, the distance between the cities is 560 kilometers.

Please note that the calculation assumes a constant speed throughout the journey and does not account for factors like traffic or variations in speed.
