A person makes 5 steps in 3 seconds. step length 75 cm. How long does it take for a person to walk the distance of 6 km 750 m?
Given: n (number of steps) = 5 steps; t1 (initial duration of movement) = 3 s; l1 (length of one step) = 75 cm (in SI l1 = 0.75 m); S2 (distance that a given person needs to travel) = 6 km 750 m (in SI S2 = 6750 m).
The required travel time is determined from the equality: S2 / t2 = V = S1 / V1 = n * l1 / t1, whence t2 = S2 * t1 / (n * l1).
Let’s calculate: t2 = 6750 * 3 / (5 * 0.75) = 5400 s = 90 minutes = 1.5 hours.
Answer: To walk a distance of 6 km 750 m, this person will need 1.5 hours.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
