Question

Из одного пункта пункта одновременно в противоположных направлениях вышли Два лыжника через 4 часа расстояние между которыми ними было 104 километра Чему равна скорость второго лыжника если скорость первого 12 километров в час

Answer 1

ВСПОМИНАЕМ
V1*t + v2*t = S = (V1+V2)*t
РЕШЕНИЕ
V2 = S/t - V1
V2= 104 : 4 - 12 =  26-12 = 14 км/час - скорость второго -
ОТВЕТ: 14 км/час

Answer 2

Solution:

Given: - Speed of the first skier, A = 12 km/h - Time taken, t = 4 hours - Distance between the skiers, d = 104 km

We can use the formula: distance = speed × time to find the speed of the second skier, B.

Calculation:

The distance covered by the first skier, A, in 4 hours is: distance A = speed A × time distance A = 12 km/h × 4 h distance A = 48 km

The remaining distance between the skiers is: remaining distance = total distance - distance A remaining distance = 104 km - 48 km remaining distance = 56 km

The speed of the second skier, B, can be calculated using the formula: speed B = remaining distance / time speed B = 56 km / 4 h speed B = 14 km/h

Answer:

The speed of the second skier is 14 km/h.
