How many km in 10 hours a person will pass moving one half of the time with a speed of 1 m / s, and the other half with a speed of 1.2 m / s, the movement is considered uniform
To find the distance traveled by the person in question, we use the formula: S = S1 + S2 = V1 * 0.5t + V2 * 0.5t.
Values of variables: V1 – the first speed of a person (V1 = 1 m / s); t – the total time of movement (t = 10 h = 36000 s); V2 – second speed of movement (V2 = 1.2 m / s).
Let’s make a calculation: S = V1 * 0.5t + V2 * 0.5t = 1 * 0.5 * 36000 + 1.2 * 0.5 * 36000 = 39600 m or 39.6 km.
Answer: A person should have covered 39.6 km in 10 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.
