Question

3. Sue's dog needs 4 hours to reach her house which is 20 km away. At what speed does it travel?

Answer 1

Ответ:

20:4=5

5 kilometers per hour

Answer 2

To find the speed at which Sue's dog travels, you can use the formula:

$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$

In this case, the distance is 20 km, and the time is 4 hours.

$\text{Speed} = \frac{20 \, \text{km}}{4 \, \text{h}}$

$\text{Speed} = 5 \, \text{km/h}$

So, Sue's dog travels at a speed of 5 kilometers per hour.
