The average velocity of Sandy is given by the total distance covered S divided by the total time taken t:
The total distance covered is
while the total time taken is 2 hours + half an hour (for the rest) + 1 hour and half, so
Therefore, the average velocity is

Answer:
a)
b)
c)
Explanation:
Given:
- diameter of hole in the tank,
- position of the hole form the tank bottom,
- initial level of turpentine in the tank before the leakage,
- level of turpentine in the tank after the repair of leakage,
- diameter of the tank,
- density of turpentine oil,
a)
Now, volume of turpentine spilled:
where:
area of the cross section of the tank's volume
b)
When the tank was full the liquid level was highest:
so velocity form the height of the hole will be given as:
<u>Now we have the flow rate of the spillage given by:</u>
c)
Total time the leak was active can be calculated as:
