Question

An airplane is traveling at a speed of 200 km/h. Identify the correct conversion factor setup required to compute the speed of the airplane in m/s. A) 200km 1hr x 1000m 1km x 1hr 60min x 60s 1min B) 200km 1hr x 1000m 1km x 1hr 60min x 1min 60s C) 200km 1hr x 1000m 200km x 1hr 60min x 1min 60s D) 200km 1hr x 1000m 200km x 1hr 60min x 60s 1min

    Answer:

    The correct conversion is B)

    B) 200km 1hr x 1000m 1km x 1hr 60min x 1min 60s

    Hence,

    200 km/h ⇒ \dfrac{200 \times 1000}{60\times 60}=55.56\ m/s

    Step-by-step explanation:

    Given:

    An airplane is traveling at a speed of 200 km/h.

    The correct conversion is B)

    B) 200km 1hr x 1000m 1km x 1hr 60min x 1min 60s

    Reason:

    For Converting  Speed unit km/h ⇒ m/s

    First we need to convert km ⇒ meter

    So 1 km = 1000 meter

    Secondly, in hour ⇒ seconds first we need to convert it into minutes then to seconds

    hour ⇒ minute ⇒  seconds

    So 1 hour = 60 minute and 1 minute = 60 seconds

    Therefore, 1 hour = 60 min × 60 sec

    Hence,

    200 km/h ⇒ \dfrac{200 \times 1000}{60\times 60}=55.56\ m/s
