Nina [5.8K]

Answer:

The temperature decreased by 9 °F in 6 days.

Step-by-step explanation:

Let the number of days it takes for the temperature to decrease by 9 °F be $x$ .

Given:

Average daily temperature decreases by $1\frac{1}{2}$ °F.

Decrease of temperature in 1 day = $1\frac{1}{2}$ = 1.5 °F.

∴ Decrease in temperature in x days is $1.5x$ .

Now, as per question, decrease in temperature in 'x' days is 9 °F.

Therefore, $1.5x=9$

$x=\frac{9}{1.5}$

$x=6$

Therefore, the temperature decreased by 9 °F in 6 days.
