Question

Из двух городов,расстояние между которыми равно 105 км одновременно в противоположном направлениях выехали два велосипедиста один из них ехал со скоростью 12 км ч а другой 15 км в час Какое расстояние будет между ними через 3 часа

Answer 1

1) 12 + 15 = 27 км/ч - скорость удаления
2) 27 * 3 = 81 км - проедут за 3 часа
3) 105 + 81 = 186 км - будет между ними через 3 часа.

Answer 2

Calculating the Distance Between Two Cyclists

To calculate the distance between the two cyclists after 3 hours, we can use the formula: distance = speed * time.

1. Calculating the Distance Traveled by the First Cyclist: - Speed of the first cyclist = 12 km/h - Time traveled = 3 hours - Using the formula: distance = speed * time - distance = 12 km/h * 3 h = 36 km

2. Calculating the Distance Traveled by the Second Cyclist: - Speed of the second cyclist = 15 km/h - Time traveled = 3 hours - Using the formula: distance = speed * time - distance = 15 km/h * 3 h = 45 km

Total Distance Between the Cyclists After 3 Hours

The total distance between the two cyclists after 3 hours can be calculated by adding the distances traveled by each cyclist.

Total distance = 36 km + 45 km = 81 km

Therefore, the distance between the two cyclists after 3 hours will be 81 kilometers.
