What is the velocity in meters per second of a runner who runs exactly 110 m toward the beah in 72 seconds?

a). 0.654 m/s toward the beach c). 15.3 m/s toward the beach
b). 1.53 m/s toward the beach d). 7920 m/s toward the beach

B). 1.53 m/s toward the beach

Explanation:

Velocity consists of a) a magnitude (the speed) and b) a direction.

The speed is given by the ratio between the distance covered and the time taken:

while the direction is given in the problem, it is the same as the displacement (toward the beach).

the answer is 12 as i may remember
