The total snowfall for listed 10 days is 349 cm.

Further explanation:

The sum of snow fell each day will give us the total snowfall for 10 days.

Given:

Snow fell on 10 days:

14 cm, 13 cm, 7 cm, 3 cm, 11 cm, 14 cm,

28 cm, 108 cm, 84 cm, 67 cm

So,

$Total\ snowfall\ for\ 10\ days\ listed=14+13+7+3+11+14+28+108+84+67\\=349\ cm$

The total snowfall for listed 10 days is 349 cm.

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
