Question

Мальчик прошёл 25км за 2ч. За сколько часов пройдёт 65км он?

Answer 1

Расстояние разделить на время = скорость
25/2 = 12.5 км/ч скорость
65/12.5 = 5,2 ч

Answer 2

To find out how many hours it will take the boy to cover 65 km, we can use a proportion based on the distance and time relationship.

Let's set up the proportion:

Distance 1 / Time 1 = Distance 2 / Time 2

where Distance 1 = 25 km Time 1 = 2 hours Distance 2 = 65 km (the distance the boy wants to cover) Time 2 = unknown (the time we need to find)

Now, plug in the values:

25 km / 2 hours = 65 km / Time 2

To find Time 2, we need to cross-multiply and then divide:

Time 2 = (25 km * 2 hours) / 65 km

Time 2 = 50 hours / 65 km

Time 2 ≈ 0.7692 hours

Now, let's convert this to minutes. Since 1 hour = 60 minutes:

Time 2 ≈ 0.7692 hours * 60 minutes/hour

Time 2 ≈ 46.15 minutes

So, the boy will take approximately 46.15 minutes to cover 65 km.
