In the streamflow lab if it takes 10 seconds for the float t

In the streamflow lab, if it takes 10 seconds for the \"float\" to travel downstream 1 meter, the velocity is:   

10

1m/s

0.1m/s

0.01m/s

Solution

given data t=10seconds

distance = 1 meter

velocity = ?

we know that velocity = distance/time

Speed upstream =d/t

= 1 / 10

= 0.1 m/sec
