# Tourists covered the first kilometer in 10 minutes, the second in 11 minutes

Tourists covered the first kilometer in 10 minutes, the second in 11 minutes, and the third in 12 minutes 20 seconds. Calculate the average tourist speed.

To calculate the average speed of tourists on three segments of the route, we use the formula: Vav = 3S / (t1 + t2 + t3).

Values of variables: S – length of each track section (S = 1 km = 1000 m); t1 – first time (t1 = 10 min = 600 s); t2 – second time (t2 = 11 min = 660 s); t3 – third time (t3 = 12 min 20 s = 740 s).

Calculation: Vav = 3 * 1000 / (600 + 660 + 740) = 1.5 m / s.

Answer: The average speed of tourists on the three sections of the route was 1.5 m / s.
