Question

Швидкість велосипедиста у 2,5 разу більша від швидкості пішохода.За 2 години пішохід долає відстань,що на 2,5км менша за відстань,яку долає велосипедист за 1годину. Знайдіть швидкість пішохода

Answer 1

х км/год швидкість пішох.

2.5х км/ год швидк. велос.

2х+2.5=2.5х

0.5х=2.5

х=5 км/год шв. пішох.

2.5х=12.5 км/год шв. велос. 

Answer 2

Calculating the Pedestrian's Speed

To find the pedestrian's speed, we can use the formula:

speed = distance / time

Given that the pedestrian covers a distance that is 2.5 km less than the distance covered by the cyclist in 1 hour, and the cyclist's speed is 2.5 times greater than the pedestrian's speed, we can set up the following equations:

1. For the cyclist: - speed_cyclist = distance_cyclist / time_cyclist

2. For the pedestrian: - speed_pedestrian = distance_pedestrian / time_pedestrian

We are given that the cyclist's speed is 2.5 times greater than the pedestrian's speed, and the pedestrian covers a distance that is 2.5 km less than the distance covered by the cyclist in 1 hour.

Let's solve for the pedestrian's speed.
