1) 1 4/5
2) 9 4/5
3) 1 1/5
4) 9.5

Respuesta :

Answer:

21 [tex]\frac{3}{5}[/tex]in/hr

Step-by-step explanation:

Distance of snow fall  = 3ft

Time taken  = 1[tex]\frac{2}{3}[/tex]hrs

Unknown:

Rate of snowfall = ?

Solution:

The rate of the snowfall is the same as the speed of the fall;

  Rate of snowfall  = [tex]\frac{distance of snowfall}{time}[/tex]

Convert the ft to inches;

             1ft  = 12inches

             3ft  = 3 x 12  = 36inches

Input the parameters and solve;

           Rate of snowfall  = [tex]\frac{36}{\frac{5}{3} }[/tex]   = 36 x [tex]\frac{3}{5}[/tex] = 21 [tex]\frac{3}{5}[/tex]in/hr
