Question

Расстояния 232 км мотоциклист проехал за 4 ч. За сколько часов он проедет 92 км, если уменьшит скорость на 12 км/ч?

Answer 1

232 : 4 = 58 ( км/час ) скорость по факту 
58 - 12 = 46 ( км/час ) уменьшенная скорость 
92 : 46 = 2 ( часа )
Ответ за 2 часа 

Answer 2

Ответ за 23 часа.1 действие 232:4=58часов-это V1
2действие 58-12=4км/ч-это V2
3действие 92:4=23часа-это t2

Answer 3

Problem Analysis

A motorcyclist has traveled a distance of 232 km in 4 hours. We need to determine how long it will take for the motorcyclist to travel a distance of 92 km if their speed is reduced by 12 km/h.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it took for the motorcyclist to travel 232 km:

Time1 = 232 km / Speed1

We are given that the motorcyclist traveled this distance in 4 hours, so we can rearrange the formula to solve for Speed1:

Speed1 = 232 km / 4 hours

Now, we need to calculate the new speed after reducing it by 12 km/h:

Speed2 = Speed1 - 12 km/h

Finally, we can calculate the time it will take for the motorcyclist to travel 92 km at the new speed:

Time2 = 92 km / Speed2

Let's plug in the values and calculate the result.

Calculation

First, let's calculate Speed1:

Speed1 = 232 km / 4 hours = 58 km/h Next, let's calculate Speed2:

Speed2 = Speed1 - 12 km/h = 58 km/h - 12 km/h = 46 km/h

Finally, let's calculate Time2:

Time2 = 92 km / Speed2 = 92 km / 46 km/h = 2 hours

Answer

If the motorcyclist reduces their speed by 12 km/h, it will take them 2 hours to travel a distance of 92 km.
