Question

Из одного пункта в противоположных направлениях выехали два велосипедиста, один со скоростью 12 км/ч, а другой со скоростью 14 км/ч. Первый велосипедист выехал на час раньше второго. Какое расстояние (в км) будет между велосипедистами через 2 часа после выезда второго велосипедиста? ДАЮ 10 БАЛЛОВ ЗА ОТВЕТ!

Answer 1

1)1+2=3 часа был в дороге 1й вел.
2)12×3=36км его путь
3)14×2=28км проехал 2й
436÷28=64км расст.между ними

Answer 2

Problem Analysis

We have two cyclists who start from the same point and travel in opposite directions. The first cyclist has a speed of 12 km/h, while the second cyclist has a speed of 14 km/h. The first cyclist starts one hour earlier than the second cyclist. We need to find the distance between the two cyclists after 2 hours from the departure of the second cyclist.

Solution

To find the distance between the two cyclists after 2 hours from the departure of the second cyclist, we can follow these steps:

1. Calculate the distance traveled by the first cyclist in 2 hours. 2. Calculate the distance traveled by the second cyclist in 2 hours. 3. Add the distances traveled by both cyclists to find the total distance between them.

Let's calculate the distances step by step:

1. Distance traveled by the first cyclist in 2 hours: - Speed of the first cyclist = 12 km/h - Time traveled by the first cyclist = 2 hours - Distance = Speed * Time = 12 km/h * 2 hours = 24 km

2. Distance traveled by the second cyclist in 2 hours: - Speed of the second cyclist = 14 km/h - Time traveled by the second cyclist = 2 hours - Distance = Speed * Time = 14 km/h * 2 hours = 28 km

3. Total distance between the two cyclists after 2 hours from the departure of the second cyclist: - Distance traveled by the first cyclist = 24 km - Distance traveled by the second cyclist = 28 km - Total distance = Distance of first cyclist + Distance of second cyclist = 24 km + 28 km = 52 km

Therefore, the distance between the two cyclists after 2 hours from the departure of the second cyclist is 52 km.

Answer

The distance between the two cyclists after 2 hours from the departure of the second cyclist is 52 km.
