Answer

Explanation:

Step1: Identify given values

The distance $d = 40\text{ km}$ and the time $t = 2\text{ hours}$.

Step2: State the speed formula

The formula for speed $v$ is distance divided by time. $$v = \frac{d}{t}$$

Step3: Calculate the speed

Substitute the given values into the formula. $$v = \frac{40\text{ km}}{2\text{ h}} = 20\text{ km/h}$$

Answer:

A. 20km/h
