Here,
Total steps taken by Magdalena = 60 steps

Time taken = 1 hour = 60 mins.

Time taken for 1st 30 steps = 20 mins

Now
time taken to complete remaining 30 steps = 60 - 20 = 40 mins = 2400 seconds.

For statment 1 -

The average number of seconds per step that Magdalena took to complete the remaining 30 steps = 2400/30 = 80

Statement 2 = 80.

Hence both statement are equal, so the option is C
