Question

The speed of a moving object is determined to be 0.06 m/s. This speed is equal to :
(a) 2.16 km/h
(b) 1.08 km/h
(c) 0.216 km/h (d) 0.0216 km/h

​

Answer 1

Answer:

The speed of a moving object is determined to be 0.06 m/s. This speed is equal to 0.216 km/h.

Explanation:

A simple way to convert a value in m/s to km/h is to multiply it with the fractional number 18/5. We know that the value of 1000 meters is equal to 1 kilometer and 3600 seconds is equal to 1 hour.

∴ 1m = 1/1000 km

    1s = 1/3600 h

⇒ 1m/1s = (1/1000) ÷ (1/3600)

             = 3600 ÷ 1000

  ∴  m/s = 18 ÷ 5 km/h

So we just need to multiply the number 0.06 with 18/5 to convert it into km/h.

0.06 m/s = 0.06 × (18/5) km/h

               = 0.216 km/h
