We can calculate the depth d of snow, in centimeters, that accumulates in harper's yard during the first h hours of a snowstorm using the equation d=5h. how many hours does it take for 11 centimeter of snow to accumulate in harper's yard? how many centimeters of snow accumulate per hour? centimeters

2.2 hours takes to accumulate 11 centimeter of snow in Harper's yard and snow accumulate per hour is 5 cm.

Step-by-step explanation:

Given:

d = 5h

where d is depth of snow in centimeters and h is hours of a snowstrom.

To find: Time when the depth of snow is 11 cm.

             Depth of snow accumulate per hour.

Consider,

d = 5h

put d = 11

11 = 5h

h = 2.2 hours

h = 2 hours 12 minutes

Now, Put h = 1

d = 5 × 1

d = 5 cm

Therefore, 2.2 hours takes to accumulate 11 centimeter of snow in Harper's yard and snow accumulate per hour is 5 cm.
