Question

ИЗ ДВУХ НАСЕЛЁННЫХ пунктов одновременно навстречу друг другу выехали два велосипедиста скорость одного 14км-ч а другого 10км-ч на сколько км они станут ближе через 1 час через пол часа какова расстояние между населёнными пунктами если через три часа велосипедисты встретились начерти

Answer 1

1) 14+10=24 км/ч-скорость сближения
2)24*1=24 км - на столько будут ближе через час
3) 24:2=12 км-на столько ближе через полчаса
4) 24*3=72 км-расстояние между пунктами

Answer 2

Problem Analysis

Two cyclists are traveling towards each other from two different locations. The speed of one cyclist is 14 km/h, and the speed of the other cyclist is 10 km/h. We need to determine how close they will be after 1 hour, after half an hour, and the distance between the two locations after 3 hours.

Solution

To find out how close the cyclists will be after a certain time, we can calculate the total distance covered by both cyclists and subtract it from the initial distance between the two locations.

Let's assume the initial distance between the two locations is D km.

# After 1 hour:

The first cyclist will cover a distance of 14 km in 1 hour, and the second cyclist will cover a distance of 10 km in 1 hour. Therefore, the total distance covered by both cyclists after 1 hour is 14 km + 10 km = 24 km.

The remaining distance between the two locations after 1 hour will be D - 24 km.

# After half an hour:

The first cyclist will cover a distance of 14 km in half an hour, and the second cyclist will cover a distance of 10 km in half an hour. Therefore, the total distance covered by both cyclists after half an hour is 7 km + 5 km = 12 km.

The remaining distance between the two locations after half an hour will be D - 12 km.

# After 3 hours:

The first cyclist will cover a distance of 14 km in 3 hours, and the second cyclist will cover a distance of 10 km in 3 hours. Therefore, the total distance covered by both cyclists after 3 hours is 42 km + 30 km = 72 km.

The remaining distance between the two locations after 3 hours will be D - 72 km.

Calculation

Let's calculate the remaining distances after 1 hour, half an hour, and 3 hours.

- After 1 hour: D - 24 km - After half an hour: D - 12 km - After 3 hours: D - 72 km

Please note that we don't have the initial distance between the two locations. If you provide the initial distance, we can calculate the remaining distances more accurately.
