Question

лыжник шёлсо скоростью 18 км/ч и был в пути 3 часа.Сколько времени понадобится пешеходу,чтобы пройти такое же растояние,если скорость в 3 раза меньше?

Answer 1

1) 18 * 3 = 54(км) прошёл лыжник за 3 часа
2) 18 : 3 = 6(км/ч) - скорость пешехода
3) 54 : 6 = 9(часов)
Ответ: 9 часов понадобится пешеходу, чтобы пройти 54км.

Answer 2

18*3=54 километра прошёл лыжник.
18:3=6 км/ч. идёт пешеход.
54:6=9 часов.
Ответ: пешеход пройдёт 54 километра за 9 часов.

Answer 3

Calculation of Time for the Pedestrian

To calculate the time it would take for a pedestrian to cover the same distance at a speed that is three times slower, we can use the formula:

Time = Distance / Speed

Given that the skier traveled at a speed of 18 km/h for 3 hours, we can calculate the distance covered by the skier:

Distance = Speed * Time

Distance = 18 km/h * 3 hours = 54 km

Now, let's calculate the time it would take for the pedestrian to cover the same distance at a speed that is three times slower:

Speed of the pedestrian = Speed of the skier / 3 = 18 km/h / 3 = 6 km/h

Time = Distance / Speed = 54 km / 6 km/h = 9 hours

Therefore, it would take the pedestrian 9 hours to cover the same distance at a speed that is three times slower than the skier's speed of 18 km/h.
