Question

If I run down the hallway 100 meters, and it takes me 20 seconds to get to the end the hallway, HOW FAST DID I RUN?

Answer 1

distance=100m

time=20sec

speed =dist/time

s=100/20

s=5m/s

Answer 2

Distance = 100 m

Time taken = 20 seconds

Speed = Distance / Time

            = 100/20

             = 5 m/s

The running speed was 5m/s.
