Question

calculate speed: a module moves 80 m in 4 s. what is the speed? formula: speed = distance / time 10 m/s 20 m/s 15 m/s

Explanation:

Step1: Identify given values

Distance $d=80\ \text{m}$, Time $t=4\ \text{s}$

Step2: Apply speed formula

$\text{Speed} = \frac{\text{distance}}{\text{time}} = \frac{80}{4}$

Step3: Calculate the result

$\text{Speed}=20\ \text{m/s}$

Answer:

20 m/s
