Given :
a spaceship launches into the air at 14550 meters in 30 minutes.
so, the distance = 14550 meters
And the time = 30 minutes
Speed = the distance over the time
Convert the time from minutes to hours
1 hour = 60 minutes
30 minutes = 0.5 hour
so, the speed will be :
[tex]\text{speed}=\frac{dis\tan ce}{time}=\frac{14550}{0.5}=29100[/tex]so, the answer is : speed = 29100 meters per hour
