Question

Два велосипедиста одновременно выехали с турбазы в противоположных направлениях. Когда между ними было 70 км,велосипедисты сделали остановку.Один проехал 36км.Другой ехал до остановки со скоростью 17 км/ч. Сколько времени велосипедисты были в пути?

Answer 1

70-36= 34

34:17=2 часа

Answer 2

Problem Analysis

Two cyclists start simultaneously from a tourist base in opposite directions. When they are 70 km apart, they stop. One cyclist travels 36 km, while the other cyclist travels at a speed of 17 km/h until they stop. We need to find out how much time the cyclists were on the road.

Solution

To find the time the cyclists were on the road, we can use the formula: time = distance / speed.

Let's calculate the time for each cyclist:

1. Cyclist 1 travels 36 km. We don't know their speed, so let's call it v1. The time taken by Cyclist 1 is given by time1 = distance1 / speed1 = 36 km / v1.

2. Cyclist 2 travels until they stop, covering a distance of 70 km. Their speed is given as 17 km/h. The time taken by Cyclist 2 is given by time2 = distance2 / speed2 = 70 km / 17 km/h.

To find the total time, we need to add the times taken by both cyclists: total time = time1 + time2.

Let's calculate the values:

1. Cyclist 1: distance1 = 36 km 2. Cyclist 2: distance2 = 70 km, speed2 = 17 km/h

Using the given values, we can calculate the time taken by each cyclist and the total time.

Calculation

1. Cyclist 1: - distance1 = 36 km - time1 = distance1 / speed1 = 36 km / v1

2. Cyclist 2: - distance2 = 70 km - speed2 = 17 km/h - time2 = distance2 / speed2 = 70 km / 17 km/h

3. Total time: - total time = time1 + time2

Let's calculate the values:

1. Cyclist 1: - distance1 = 36 km - time1 = 36 km / v1

2. Cyclist 2: - distance2 = 70 km - speed2 = 17 km/h - time2 = 70 km / 17 km/h

3. Total time: - total time = time1 + time2

Answer

The total time the cyclists were on the road is given by the sum of the times taken by each cyclist.
