In a lake a remote controlled submarine moved norweast at a constant velocity. It moved 935 centimeters in 10.0 seconds. What was its velocity

Answer: 93.5 m/s

Explanation:

Velocity is the rate of change of displacement per unit time. It is measured in metres per second.

i. e velocity = Displacement / Time taken

In this case,

Displacement = 935 centimeters north west

(Convert centimeters to metres)

Recall that 100cm = 1m

935 cm = 935/100 = 9.35m

Time taken = 10.0 seconds.

So, velocity = Displacement / Time taken

Velocity = 9.35 metres x 10.0 seconds

Velocity = 93.5 m/s

Thus, the velocity of the submarine moving north west is 93.5 m/s
