Question

Расстояние между двумя туристическими базами 22.5 км.Из этих баз одновременно навстречу друг другу вышли два туриста. Один из них идёт со скоростью 4.3 км/ч, а другого 4.7 км/ч. Какое расстояние будет между туристами через 1ч? через 1.5 ч? Через сколько часов они встретятся?

Answer 1

4,3+4,7=9 км/ч скорость сближения туристов
22,5:9=2,5ч -время через которое они встретятся
9*1=9 км пройдут за 1 час
9*1,5=13,5 км пройдут за 1,5 часа
22,5-9=13,5 км будет между ними через 1 час
22,5-13,5=9 км будет между ними через 1,5 часа

Answer 2

Calculation of Distance between Tourists

To calculate the distance between the two tourists after a certain amount of time, we can use the formula:

Distance = Speed × Time

Given that one tourist is walking at a speed of 4.3 km/h and the other tourist is walking at a speed of 4.7 km/h, we can calculate the distance between them after 1 hour, 1.5 hours, and the time it takes for them to meet.

1. After 1 hour: - Tourist 1: Distance = 4.3 km/h × 1 h = 4.3 km - Tourist 2: Distance = 4.7 km/h × 1 h = 4.7 km - The distance between the tourists after 1 hour is 4.3 km + 4.7 km = 9 km.

2. After 1.5 hours: - Tourist 1: Distance = 4.3 km/h × 1.5 h = 6.45 km - Tourist 2: Distance = 4.7 km/h × 1.5 h = 7.05 km - The distance between the tourists after 1.5 hours is 6.45 km + 7.05 km = 13.5 km.

3. To calculate the time it takes for the tourists to meet, we need to find the time it takes for them to cover the initial distance of 22.5 km. - Total speed = 4.3 km/h + 4.7 km/h = 9 km/h - Time = Distance / Speed = 22.5 km / 9 km/h = 2.5 hours

Therefore, the tourists will meet each other after 2.5 hours.

Please note that the above calculations are based on the given speeds and assume a constant speed throughout the journey.
