Answer: The spacecraft traveled 345 km during the given time.
Step-by-step explanation:
To calculate the distance of spacecraft, we use the equation:
![\text{Velocity}=\frac{\text{Distance}{\text{Time}}]()
We are given:
Velocity = 2.3 km/sec
Time = 2.5 mins = 150 sec (Conversion factor: 1 min = 60 sec)
Putting values in above equation, we get:

Hence, the spacecraft traveled 345 km during the given time.
