Answer:
5/9 m/min
Step-by-step explanation:
The depth of the water is 2/5 of the depth of the trough, so the width of the surface will be 2/5 of the width of the trough:
2/5 × 2 m = 4/5 m
Then the surface area of the water is ...
A = LW = (18 m)(4/5 m) = 14.4 m²
The rate of change of height multiplied by the area gives the rate of change of volume:
8 m³/min = (14.4 m²)(h')
h' = (8 m³/min)/(14.4 m²) = 5/9 m/min
Answer:
225 minutes or 3 hours and 45 minutes
Step-by-step explanation:
45 (minutes per day) times 5 (days in a school week) = 225 minutes
or add 45 (minutes per day)+ 45+45+45+45 = 225
To get the hours:
Divide 225 by 60 (minutes per hour) and it is 3 - remainder 45.
