Which of the following statements is true? A spending variance is the difference between the amount of the cost in the static planning budget and the amount of the cost in the flexible budget. A revenue variance is the difference between what the total sales revenue should be, given the actual level of activity of the period, and the actual total sales revenue. A revenue variance is unfavorable if the revenue in the static planning budget is less than the revenue in the flexible budget.

Question:  You are asked to test an underground pipe with clean water steadily flowing through. The pipe starts with a large cross sectional area of 450 cm2 and after few meters the presence of debris creates a constriction reducing the pipe cross sectional area to 250 cm2. You are able to check the water speed at the 450 cm2 area and you measure 5 m/s.  Assuming that the water flow is steady, what do you expect to be the water speed at the constriction?
