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

Find the present balance.

Triss [41]

<h3>Credited balance:-</h3>

$\\ \rm\longmapsto 115.90+115.90+345.85$

$\\ \rm\longmapsto 231.80+345.85$

$\\ \rm\longmapsto 577.65$

<h3>Debited amount:-</h3>

$\\ \rm\longmapsto 25.85+2.00$

$\\ \rm\longmapsto 27.85$

<h3>Checked amount:-</h3>

$\\ \rm\longmapsto 19.45+21.02+95.98$

$\\ \rm\longmapsto 117+19.45$

$\\ \rm\longmapsto 136.45$

<h3>Total change in balance</h3>

$\\ \rm\longmapsto 577.65-(27.85+136.45)$

$\\ \rm\longmapsto 577.65-191.3$

$\\ \rm\longmapsto 386.35$

Now

<h3>Current balance</h3>

$\\ \rm\longmapsto 386.35+271.31$

$\\ \rm\longmapsto\$ 657.66$
