A yacht that travels 1.375 km in 165 minutes expressed in km/h
Tomtit [17]

The speed of a yacht traveling a distance of 1.357 km in 165 minutes is 0.5 km/h

<h3>What is Speed?</h3>

The speed of an object is the distance covered by the object in respect to time.

Mathematically:

\mathbf{Speed = \dfrac{distance}{time}}

\mathbf{Speed = \dfrac{1.375 \ km}{165 minutes }}

  • We know that 60 minutes = 1 hour
  • 165 minutes = 2.75 hours

\mathbf{Speed = \dfrac{1.375 \ km}{2.75 \ hours}}

Speed = 0.5 km/hour
