What distance will a pedestrian travel in 2 hours moving at a speed of 120 cm / s?

Given:

t = 2 hours – pedestrian travel time;

v = 120 centimeters per second – the speed of the pedestrian.

It is required to determine L (meter) – how much distance a pedestrian will walk in a time interval t.

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

v = 120 cm / s = 120 * 10-2 = 1.2 meters per second.

Let’s convert time units from hours to seconds:

t = 2 hours = 2 * 3600 = 7200 seconds.

Then the distance will be equal to:

L = v * t = 1.2 * 7200 = 8640 meters (approximately 8.6 kilometers).

Answer: in 2 hours a pedestrian will cover a path equal to 8640 meters.
