Answer 1

1). 0.2 hours

2). 5 centimters per hour

Explanation:

Equation which represents the depth 'd' of snow accumulated in Harper's yard during 'h' hours will be,

d = 5h

If depth of snow accumulated = 1 cm

From the given equation,

1 = 5h

h =
`(1)/(5)` = 0.2 hours

If duration of the snowfall = 1 hour

d = 5×1 = 5 centimeter

Therefore, snow accumulated per hour = 5 centimeters.
