Question

Из одного города в противоположных направлениях одновременно выехали велосипедист и мотоциклист Спустя некоторое время велосипедист преодолел 42 км,а мотоциклист-на 89 км больше,Найди расстояние между ними в этот момент

Answer 1

42+89=131 км - преодолел мотоциклист

 

Т.к. ехали они в противоположных направлениях, значит общее расстояние м/у ними = сумме расстояний, которые они преодолели:

 

42+131=153 км - расстояние м/у ними

Answer 2

42+89=131км проехал мотоциклист

131+42=173км расстояние между мотоциклистом и велосипедистом

Answer 3

Problem Analysis

We are given that a cyclist and a motorcyclist start simultaneously from the same city in opposite directions. After some time, the cyclist has covered a distance of 42 km, while the motorcyclist has covered a distance that is 89 km more than the cyclist. We need to find the distance between them at this moment.

Solution

Let's assume that the distance between the cyclist and the motorcyclist at the start is x km. After some time, the cyclist has covered 42 km, so the distance between them has increased by 42 km. At the same time, the motorcyclist has covered a distance that is 89 km more than the cyclist. Therefore, the distance between them is now x + 42 km for the cyclist and x + 42 + 89 km for the motorcyclist.

To find the distance between them at this moment, we can subtract the distance covered by the cyclist from the distance covered by the motorcyclist:

Distance between them = (x + 42 + 89) - (x + 42)

Simplifying the expression:

Distance between them = x + 42 + 89 - x - 42

The x terms cancel out, leaving us with:

Distance between them = 89

Therefore, the distance between the cyclist and the motorcyclist at this moment is 89 km.

Answer

The distance between the cyclist and the motorcyclist at this moment is 89 km.
