David did not have time to wait for the elevator on the first floor of the building so he decided to go up the stairs. If it took him 2 minutes to get to the third floor, how long will it take him to get to the ninth floor?

Respuesta :

Answer:

6 minutes

Step-by-step explanation:

so it took him 2 mins from floor 1 to 3 then another to 3 to 6 so now it's been 4 mins then 6 to 9 is another 2 mins and that equals 6 minutes

Answer:

8 minutes

Step-by-step explanation:

It takes 2 minutes every 2 floors, and Floor 9 is 8 floors away from Floor 1, so 2x4=8.
