Answer 1

The first ship has the same speed as Saige's ship while the second and third do not have the same speed.

Explanation:

d = Distance traveled by Saige's spaceship = 588 km

t = Time taken = 60 seconds

Speed is given by

`s=(d)/(t)\\\Rightarrow s=(588)/(60)\\\Rightarrow s=9.8\ \text{km/s}`

The other ships

`s=(441)/(45)=9.8\ \text{km/s}`

`s=(215)/(25)=8.6\ \text{km/s}`

`s=(649)/(110)=5.9\ \text{km/s}`

So, the first ship has the same speed as Saige's ship while the second and third do not have the same speed.
