With uniform movement, a pedestrian covers 8 km in 4 seconds. what path will it cover when moving at the same speed in 3 s?
To determine the path. passed by a given pedestrian, we use the equality: S1 / t1 = V (constant pedestrian speed) = S2 / t2, whence S2 = S1 * t2 / t1.
The meaning of the variables: S1 – the first distance (S1 = 8 m); t1 – the first elapsed time (t1 = 4 s); t2 – second time (t2 = 3 s).
Calculation: S2 = S1 * t2 / t1 = 8 * 3/4 = 6 m.
Answer: The pedestrian had to walk 6 m.
