Question

Расстояние от города до деревни 62 километров из города со скоростью 14 километров час выехал велосипедист А ему навстречу в это же время из деревни выехал второй велосипедист два велосипедиста и встретились через 2 часа после начала движения с какой скоростью двигался велосипедист

Answer 1

1. 62:2=31(общая скорость сближения)
2. 31-14=17
Ответ: 17 км/ч скорость второго велосипедиста

Answer 2

62:2=31 (км/ч) сумма скоростей или скорость сближения
31-14=17 (км/ч)
Ответ: скорость второго велосипедиста равна 17 км/ч

Answer 3

Problem Analysis

We are given that the distance between a city and a village is 62 kilometers. A cyclist, A, starts from the city and travels towards the village at a speed of 14 kilometers per hour. At the same time, another cyclist starts from the village and travels towards the city. The two cyclists meet each other after 2 hours. We need to determine the speed at which the second cyclist is traveling.

Solution

Let's assume the speed of the second cyclist is v kilometers per hour.

Since the two cyclists meet each other after 2 hours, we can calculate the total distance covered by cyclist A in 2 hours using the formula:

Distance = Speed × Time

The distance covered by cyclist A in 2 hours is:

Distance_A = Speed_A × Time_A = 14 km/h × 2 h = 28 km Similarly, the distance covered by the second cyclist in 2 hours is:

Distance_B = Speed_B × Time_B = v km/h × 2 h = 2v km

Since the total distance between the city and the village is 62 kilometers, we can write the equation:

Distance_A + Distance_B = Total Distance

Substituting the values we calculated:

28 km + 2v km = 62 km

Simplifying the equation:

2v = 62 - 28

2v = 34

v = 34/2

v = 17 km/h

Therefore, the second cyclist is traveling at a speed of 17 kilometers per hour.

Answer

The second cyclist is traveling at a speed of 17 kilometers per hour.
