Answer:
72.033 ft
Step-by-step explanation:
To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.
[tex]\frac{18.47}{1}=\frac{y}{3.9}[/tex]
Step 1: Switch sides
[tex]\frac{y}{3.9}=\frac{18.47}{1}[/tex]
Step 2: Apply rule: [tex]\frac{a}{1}=a[/tex]
[tex]\frac{y}{3.9}=18.47[/tex]
Step 3: Multiply both sides by [tex]3.9[/tex]
[tex]\frac{3.9y}{3.9}=18.47\cdot \:3.9[/tex]
Step 4: Simplify
[tex]y=72.033[/tex]
The bear can run 72.033 feet in 3.9 seconds
