Question

Велосипедист за несколько часов проехал 36 км. А) Сколько километров пройдёт за то же время пешеход, скорость которого в 3 раза меньше скорости велисипедиста? Б) Сколько километров проедет за то же время мотоциклист, скорость которого в 5 раз больше скорости велисипедиста?

Answer 1

1)36:3=12км/ч-прошел пешеход
2)36*5=180км/ч
Ответ :12км/ч,180км/ч

Answer 2

Question A: Сколько километров пройдёт за то же время пешеход, скорость которого в 3 раза меньше скорости велосипедиста?

To find out how many kilometers a pedestrian will travel in the same amount of time as the cyclist, we need to compare their speeds. Given that the pedestrian's speed is 3 times slower than the cyclist's speed, we can calculate the distance the pedestrian will cover using the formula:

Distance = Speed × Time

Let's assume the cyclist's speed is represented by v km/h, and the time taken by both the cyclist and the pedestrian is the same. Since the pedestrian's speed is 3 times slower, their speed can be represented as v/3 km/h.

Substituting the values into the formula, we get:

Distance_pedestrian = (v/3) × Time

Since the cyclist covered 36 km in the given time, we can substitute the distance and solve for the time:

36 = v × Time

Solving for Time, we get:

Time = 36/v

Substituting this value back into the equation for the pedestrian's distance, we get:

Distance_pedestrian = (v/3) × (36/v) = 12 km

Therefore, the pedestrian will cover 12 km in the same amount of time as the cyclist.
