What is a speed of 55 mph equivalent to in units of m/s? ( 1 mile = 1609 m, 1 hour = 3600 s)

Respuesta :

9514 1404 393

Answer:

  about 24.58 m/s

Step-by-step explanation:

Multiply by conversion factors that change the units, but not the value.

  (55 mi/h) × (1609 m/mi) × (1 h)/(3600 s) = (55×1609/3600) m/s

  = 88495/3600 m/s ≈ 24.58 m/s
