Question

A staircase of 123 steps starts from the ground floor and goes down to the cellar. If Tamara leaves the cellar and goes up the 3 by 3 steps, how many long steps will she have to take to get to the first floor?

A) 121
B) 122
C) 123
D) 124

Answer 1

Tamara will need to take 41 long steps to reach the first floor.

Step-by-step explanation:

To calculate the number of long steps Tamara will have to take to reach the first floor, we need to determine how many 3-step increments she will need. Given that the staircase has 123 steps and she goes up 3 steps at a time, we can divide 123 by 3 to find the number of 3-step increments. 123 ÷ 3 = 41. Therefore, Tamara will need to take 41 long steps to reach the first floor.
