Question

Расстояние между городами 144 км Велосипедист проезжает это расстояние за 12 часов а мотоциклист в 3 раз быстрее если не знаете городов выехали одновременно навстречу друг другу через сколько часов встретятся

Answer 1

12÷3=4 часа ехал мотоциклист от города до города.
144÷12= 12 км в час скорость велосипедист
144÷4= 36 км в час скорость мотоциклист
144÷(36+12)=3 часа встретятся велосипедист с мотоциклистом.

Answer 2

144 делим на 12 потом полученое умножаем с 3 получаем скорость 

Answer 3

Problem Analysis

We are given that the distance between two cities is 144 km. A cyclist covers this distance in 12 hours, while a motorcyclist is three times faster. We need to determine how long it will take for them to meet if they start simultaneously and travel towards each other.

Solution

Let's calculate the speeds of the cyclist and the motorcyclist first.

The cyclist covers the distance of 144 km in 12 hours, so their speed is: Speed of cyclist = Distance / Time = 144 km / 12 hours = 12 km/h.

The motorcyclist is three times faster than the cyclist, so their speed is: Speed of motorcyclist = 3 * Speed of cyclist = 3 * 12 km/h = 36 km/h.

Now, we can calculate the time it will take for them to meet. Since they are traveling towards each other, their combined speed is the sum of their individual speeds: Combined speed = Speed of cyclist + Speed of motorcyclist = 12 km/h + 36 km/h = 48 km/h.

To find the time it takes for them to meet, we can use the formula: Time = Distance / Combined speed = 144 km / 48 km/h = 3 hours.

Therefore, the cyclist and the motorcyclist will meet after 3 hours.

Answer

The cyclist and the motorcyclist will meet after 3 hours.
