The hippodrome circle is 800m long. Moving at a trot, the horse develops a speed of 4 m / s at a canter of 6 m / s, how much faster the horse passes 3 circles at a gallop than at a trot.

1) Find out what the distance of 3 circles of the hippodrome is equal to: 800 · 3 = 2400 (m);
2) Let’s calculate how long it takes a horse to overcome 3 circles, moving at a trot (at a speed of 4 m / s): 2400: 4 = 600 (s);
3) Determine how many seconds a horse will run 3 laps, moving at a gallop (with a speed of 6 m / s): 2400: 6 = 400 (s);
4) Find out how much faster the horse goes 3 laps at a gallop than the same distance, moving at a trot: 600 – 400 = 200 (s).
Answer: 200 seconds faster the horse will run 3 laps of the racetrack at a gallop than at a trot.
