Question

Из двух поселков растояние между которыми 44км одновременно в одном направлении выехали два мотоциклиста со скоростями 46 км/ч и 35 км/ч на сколько километров уменьшится расстояние между ними через 1ч 2ч 3ч через 4ч?ришишь дам 15 балов

Answer 1

46-35=11км/ч-скорость сближения
через 1 часа    44-11=33км
через два часа  44-2*11=44-22=22км
через три часа 44-3*11=11км
через 4 часа  44-4*11=0км догонит

Answer 2

Problem Analysis

We have two motorcyclists who start simultaneously from two villages that are 44 km apart. The first motorcyclist has a speed of 46 km/h, and the second motorcyclist has a speed of 35 km/h. We need to calculate how much the distance between them will decrease after 1 hour, 2 hours, 3 hours, and 4 hours.

Solution

To find the distance between the two motorcyclists after a certain time, we need to calculate the distance covered by each motorcyclist and subtract it from the initial distance of 44 km.

Let's calculate the distance covered by each motorcyclist after a given time:

1. After 1 hour: - The first motorcyclist covers a distance of 46 km/h * 1 h = 46 km. - The second motorcyclist covers a distance of 35 km/h * 1 h = 35 km. - The distance between them will decrease by 46 km + 35 km = 81 km.

2. After 2 hours: - The first motorcyclist covers a distance of 46 km/h * 2 h = 92 km. - The second motorcyclist covers a distance of 35 km/h * 2 h = 70 km. - The distance between them will decrease by 92 km + 70 km = 162 km.

3. After 3 hours: - The first motorcyclist covers a distance of 46 km/h * 3 h = 138 km. - The second motorcyclist covers a distance of 35 km/h * 3 h = 105 km. - The distance between them will decrease by 138 km + 105 km = 243 km.

4. After 4 hours: - The first motorcyclist covers a distance of 46 km/h * 4 h = 184 km. - The second motorcyclist covers a distance of 35 km/h * 4 h = 140 km. - The distance between them will decrease by 184 km + 140 km = 324 km.

Answer

The distance between the two motorcyclists will decrease by: - 81 km after 1 hour - 162 km after 2 hours - 243 km after 3 hours - 324 km after 4 hours
