Question

скорость лошади 15км/ч,скорость пешехода в 3 раза меньше.сколько времени потребуется пешеходу,чтобы пройти 20км?30км?какое расстояние пройдёт лошадь за 3ч?за 4ч?

Answer 1

15:3=5 (км/ч) - скорость пешехода

20:5=4 (ч.) - потребуется пешеходу,чтобы пройти 20км

30:5=6 (ч.) - потребуется пешеходу,чтобы пройти 30км

15*3=45 (км) - пройдет лошадь за 3 часа

15*4=60 (км) - пройдет лошадь за 4 часа

Answer 2

1) 15/3=5(км\ч)  - скорость пешехода. 

2) 20/5= 4(ч)

3) 30/5=6(ч)

4) 15*3= 45(км)

5) 15*4= 60(км) 

 

Answer 3

Calculation of Time Required for the Pedestrian to Cover a Distance

Given: - Speed of the horse: 15 km/h - Speed of the pedestrian: 3 times less than the horse's speed

To calculate the time required for the pedestrian to cover a distance, we can use the formula:

Time = Distance / Speed

Let's calculate the time required for the pedestrian to cover a distance of 20 km and 30 km.

For a distance of 20 km: - Speed of the pedestrian = Speed of the horse / 3 = 15 km/h / 3 = 5 km/h - Time = 20 km / 5 km/h = 4 hours For a distance of 30 km: - Speed of the pedestrian = Speed of the horse / 3 = 15 km/h / 3 = 5 km/h - Time = 30 km / 5 km/h = 6 hours Therefore, it will take the pedestrian 4 hours to cover a distance of 20 km and 6 hours to cover a distance of 30 km.

Distance Covered by the Horse in 3 Hours and 4 Hours

To calculate the distance covered by the horse in 3 hours and 4 hours, we can use the formula:

Distance = Speed * Time

Let's calculate the distance covered by the horse in 3 hours and 4 hours.

For 3 hours: - Distance = Speed of the horse * Time = 15 km/h * 3 hours = 45 km For 4 hours: - Distance = Speed of the horse * Time = 15 km/h * 4 hours = 60 km Therefore, the horse will cover a distance of 45 km in 3 hours and 60 km in 4 hours.
