Three elephants are standing on a very very strong bridge. the bridge happens to have marks at every meter along the way (almost like it was meant for setting up a physics problem). elephant#1 is standing at 4 meters and starts walking. he walks for 30 seconds, the elephant is at the place on the bridge marked 64 meters. what is elephant#1's speed? l

Mary Haley · Answer 1

Speed = (distance covered) / (time to cover the distance).

Distance covered = (mark at the end) minus (mark at the beginning)

= (64m - 4m) = 60 meters.

Speed = (60 meters) / (30 seconds) = 2 meters/second.

We don't care about the bridge or the other two elephants.

They don't have any effect on the question or the answer.
