Question

Велосипедист и мотоциклист выехали одновременно из двух посёлков на встречу друг к другу.Велосипидист со скоростью 15 км\ч а мотоциклист со скоростью 57 км\ч.Расстояние между посёлками 288 км.Какое расстояние будет между ними через 3 часа осле начало движения

Answer 1

1. 15+57=72 км/ч (скорость сближения)
2. 288:72=4 ч (время до встречи)
3. 72х3=216 км (будет расстояние между ними через 3 часа)

Answer 2

Calculation of Distance Traveled

To calculate the distance between the cyclist and the motorcyclist after 3 hours, we need to determine how far each of them will travel in that time.

The cyclist is traveling at a speed of 15 km/h, so in 3 hours, they will cover a distance of 45 km (15 km/h * 3 h).

Similarly, the motorcyclist is traveling at a speed of 57 km/h, so in 3 hours, they will cover a distance of 171 km (57 km/h * 3 h).

Calculation of Remaining Distance

After 3 hours, the cyclist and the motorcyclist will have covered a total distance of 216 km (45 km + 171 km).

Since the total distance between the two villages is 288 km, we can calculate the remaining distance by subtracting the distance covered from the total distance:

Remaining distance = Total distance - Distance covered Remaining distance = 288 km - 216 km Remaining distance = 72 km

Therefore, after 3 hours, the cyclist and the motorcyclist will be 72 km apart from each other.
