Find the velocity in meters per second of a swimmer who swims 110 meters toward the shore in 72 seconds

1.527 m/s

Explanation:

Here we assume that swimmer's initial speed is 0. and he is accelerating in same acceleration through out the motion And we can use motion equations to solve the questions. Symbols has usual meanings

velocity = distance / time

              = 110/72

V = 1.527 m/s

double the distance = divide strength by 4

the answer is b, have negligible mass
