Answer 1

Вначале вычисляем скорость =7.2/2.4=3км/ч. Далее второе и последнее действие 3*1.6=4.8км/ч.-ответ

Answer 2

Problem:

A boy walked 7.2 km in 2.4 hours. How far will he walk in 1.6 hours?

Solution:

To find out how far the boy will walk in 1.6 hours, we can set up a proportion using the given information.

Let's assume that the distance the boy will walk in 1.6 hours is x km.

We can set up the proportion as follows:

2.4 hours / 7.2 km = 1.6 hours / x km

To solve for x, we can cross-multiply and then divide:

2.4 hours * x km = 1.6 hours * 7.2 km

2.4x = 11.52

Dividing both sides by 2.4, we get:

x = 11.52 / 2.4

x ≈ 4.8 km

Therefore, the boy will walk approximately 4.8 km in 1.6 hours.
