Question

To climb each step, Kimberly takes 3 minutes more than Susan. How many minutes will Kimberly need to climb steps 3 and 4 on the ladder?

• A. 7 min, 11 min
• B. 9 min, 11 min
• C. 7 min, 9 min
• D. 11 min, 13 min

Answer 1

The correct option is C 7 min, 9 min

Kimberly takes 3 more minutes than Susan to climb the ladder.

Let's follow the same pattern to find the time taken by Kimberly to climb third and fourth ladder steps.


To climb $3^{rd}$ step, Kimberly will take 4 + 3 = 7 minutes.

For the $4^{th}$ step, Kimberly will take 6 + 3 = 9 minutes.
