Solution

The correct option is C 30 T
Time period of seconds pendulum is $2 s e c o n d s$ i.e. $T = 2$ seconds
Thus, $t = 1 m i n u t e = 60 s e c o n d s = 30 \times 2 s e c o n d s = 30 T$

On one of the escalators on the Paris metro, Maria finds that if she walks down 26 steps she needs 30 seconds to get to the bottom, but if on another trip she makes 34 steps, then she needs only 18 seconds to reach the bottom. If the time is measured from the instant that the top step begins to descend until the time Maria steps off the last step at the bottom onto the level platform, what is the height of the stairway in steps and how many seconds does it take the escalator to travel one step?
