From Moscow to St. Petersburg the plane flew at a speed of 800 km / h and back

From Moscow to St. Petersburg the plane flew at a speed of 800 km / h and back at a speed of 250 m / s in which direction the plane flew faster?

To compare the speeds of aircraft movement from Moscow to St. Petersburg and back, let’s convert the speed of movement from Moscow to St. Petersburg equal to 800 km / h into the system speed units in m / s in accordance with the SI system: 800 km / h (1 km = 1000 m, 1 h = 3600 s) = 800 * 1000/3600 = 222.2 m / s.
Answer: Since 250 m / s> 222.2 m / s, the plane flew faster in the opposite direction (from St. Petersburg to Moscow).
