Question

Из двух сел навстречу друг другу выехали на лыжах Дед Мороз и Снегурочка. скорость Снегурочки 20 км/ч а скорость деда мороза на 5 км/ч меньше. они встретелись мпустя 3 часа после выезда. сколько клометров было между ними сначала?

Answer 1

20+(20-5)=35км /ч их общая скорость
35*3=105 км было между нами сначала

2 способ 20*3=60км проехала снегурочка
(20-5)*3=45 км проехал ДМ
60+45=105км было между ними

Answer 2

Скорость деда мороза 20-5=15. они встретились через 3 часа значит их скорости умножаем на 3. 20*3=60 столько проехала снегурочка. 15*3=45 столько проехал дед мороз. 45+60=105км между ними с начало было 105 км.   А дед мороз не мужик слабее снегурочки 

Answer 3

Calculation of the Distance Between Ded Moroz and Snegurochka

To calculate the distance between Ded Moroz and Snegurochka, we need to consider their speeds and the time it took for them to meet.

Given: - Snegurochka's speed: 20 km/h - Ded Moroz's speed: 5 km/h less than Snegurochka's speed - They met 3 hours after starting their journey

To find the distance between them, we can use the formula:

Distance = Speed × Time

Let's calculate the distance step by step:

1. Ded Moroz's speed: Since Ded Moroz's speed is 5 km/h less than Snegurochka's speed, his speed would be 20 km/h - 5 km/h = 15 km/h.

2. Distance covered by Snegurochka: Snegurochka's speed is 20 km/h, and she traveled for 3 hours. So, the distance covered by Snegurochka is 20 km/h × 3 hours = 60 km.

3. Distance covered by Ded Moroz: Ded Moroz's speed is 15 km/h, and he also traveled for 3 hours. So, the distance covered by Ded Moroz is 15 km/h × 3 hours = 45 km.

4. Total distance between Ded Moroz and Snegurochka: The total distance between them is the sum of the distances covered by each of them. Therefore, the total distance is 60 km + 45 km = 105 km.

So, the initial distance between Ded Moroz and Snegurochka was 105 kilometers.
