Solution TASK n.6. Diego and Manu . Teacher Edelmira Riero. CPR ALCA- SPAIN from COLEGIO ALCA on Vimeo.

 

Up to the second floor is 115m in a straight line; Walking up the elevator to the second floor.
the number of steps are numbered and are as follows: To the first floor: 329 stairs
From the first to the second floor: 341 stairs
Total 670 stairs
if the average rise time of a step is a second, then climb 670 steps would be 670 seconds, about 11 minutes.

As the rise time elevator to the second floor we demonstrated that it was 1 minute; the second group would remain in the cafeteria about 10 mitnutos.

but...

Where is it written that a person goes a step per second?
We look forward to that we answer this last question
