A. 90 000 s
B. 9000 s
C. 900 s
D. 90 s

Answer 1

Option C

Step-by-step explanation:

Your answer is option C or "900 seconds."

If the missile rises at a rate of 10 meters per second and we want to know how long, it will take for the missile to reach 9000 meters. We simply multiply the options given by 10 in till we found the option that reaches the height we want for our missile.


`90000*10=900000`

`9000*10=90000`

`900*10=9000`

Takes 900 seconds for the missile to reach 9000 meters.

Hope this helps.
