Question

Велосипедист догнал пешехода в 15 ч. Какое расстояние было между ними в 14 ч, если скорость пешехода- 4,92 км/ч, а скорость велосипедиста - 12,4 км/ч

Answer 1

Время нагона 15-14= 1 час скорость нагона 12.4-4.92 =7,48 км/ч                          расстояние между ними в 14 час =1 час *7,48 км/ч    =7,48 км

Answer 2

Problem Analysis

We are given the information that a cyclist caught up to a pedestrian at 15:00. We need to determine the distance between them at 14:00, given that the pedestrian's speed is 4.92 km/h and the cyclist's speed is 12.4 km/h.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's calculate the distance between the cyclist and the pedestrian at 15:00 using the given speeds and time: - Pedestrian's speed: 4.92 km/h - Cyclist's speed: 12.4 km/h - Time: 15:00 - 14:00 = 1 hour

Using the formula, we can calculate the distance between them at 15:00: - Distance = Pedestrian's speed × Time = 4.92 km/h × 1 hour = 4.92 km

Therefore, at 15:00, the distance between the cyclist and the pedestrian is 4.92 km.

Answer

The distance between the cyclist and the pedestrian at 14:00 is 4.92 km.
