Answer to Question #159616 in Algebra for Indy Leenders

Question

A farmer hears a weather report saying that temperatures will be decreasing approximately 6∘ 6∘ every hour for the next 3 hours. What signed number represents the total change in temperature expected over the next 3 hours?

Answer 1

As the question states that the temperature falls by $6.6 \degree$ every hour.

Temperature falling in next $3$ hours $= 6.6\degree \times 3 = 19.8\degree$

Hence in the next three hours the temperature will fall by $19.8\degree$ .
