4,92 км/ч-скорость пешехода.
12,4 км/ч-скорость велосипедиста.
1 час-время.
(4,92+12,4)*1=17,32

Answer 3

Calculating the Distance Between the Pedestrian and the Cyclist

To calculate the distance between the pedestrian and the cyclist at 14:00, we can use the formula: distance = speed × time.

Given: - Pedestrian's speed = 4.92 km/h - Cyclist's speed = 12.4 km/h - Time elapsed = 1 hour (from 14:00 to 15:00)

Using the formula, we can calculate the distance between them at 14:00.

Calculation

For the pedestrian: - distance_pedestrian = speed_pedestrian × time - distance_pedestrian = 4.92 km/h × 1 h - distance_pedestrian = 4.92 km

For the cyclist: - distance_cyclist = speed_cyclist × time - distance_cyclist = 12.4 km/h × 1 h - distance_cyclist = 12.4 km

At 14:00, the distance between the pedestrian and the cyclist was: distance_cyclist - distance_pedestrian = 12.4 km - 4.92 km = 7.48 km.

So, at 14:00, the distance between the pedestrian and the cyclist was 7.48 kilometers.
