Under water, penguins develop a speed of 30 km / h. Determine how far a penguin swims in 5 seconds.

v = 30 kilometers per hour – the speed that penguins develop under water;

t = 5 seconds – time span.

It is required to determine what distance S (meters) the penguin will swim in time t.

Let’s convert the units of measurement of speed from kilometers per hour to meters per second:

v = 30 km / h = 30 * 10/36 = 300/36 = 8.3 meters per second.

Then the distance will be equal to:

S = v * t = 8.3 * 5 = 41.5 meters.

Answer: in 5 seconds, the penguin will swim a distance of 41.5 meters.
