Answer:
1). 0.2 hours
2). 5 centimters per hour
Step-by-step 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 = [tex]\frac{1}{5}[/tex] = 0.2 hours
If duration of the snowfall = 1 hour
d = 5×1 = 5 centimeter
Therefore, snow accumulated per hour = 5 centimeters.
