Answer: 9 cm.
Step-by-step explanation:
You are given that increase in snow level are recorded with positive numbers while it is recorded with negative number when it is decreasing.
The initial depth of the snow is 10 cm
The rate = 1/3 cm/h
Time t = 3 hours
Using the formula
Rate = depth / time
Substitute the rate and the time into the formula
1/3 = depth/3
Cross multiply
Depth = 3 × 1/3
Depth = 1 cm
The depth of the snow on Cherry street after 3 hours will be
10cm - 1 cm = 9 cm.
