Answer:
The first ship has the same speed as Saige's ship while the second and third do not have the same speed.
Step-by-step explanation:
d = Distance traveled by Saige's spaceship = 588 km
t = Time taken = 60 seconds
Speed is given by
[tex]s=\dfrac{d}{t}\\\Rightarrow s=\dfrac{588}{60}\\\Rightarrow s=9.8\ \text{km/s}[/tex]
The other ships
[tex]s=\dfrac{441}{45}=9.8\ \text{km/s}[/tex]
[tex]s=\dfrac{215}{25}=8.6\ \text{km/s}[/tex]
[tex]s=\dfrac{649}{110}=5.9\ \text{km/s}[/tex]
So, the first ship has the same speed as Saige's ship while the second and third do not have the same speed.
