A pedestrian covered a circle with a radius of 3 km in 1.5 hours. In this case, the average speed of a pedestrian was?

Given:
r (env) = 3 (km)
t (walk) = 1.5 (h)
V (Wed) -?
Decision:
C = 2пr = (2 * 3.14) * 3 = 6.28 * 3 = 18.84 (circumference)
V (Wed) = s / t = 18.84 / 1.5 = 12.56 (km / h)
Answer: The average walking speed is 12.56 km / h.
