Answer
[tex] \boxed {64} [/tex]
Detailed Explanation
Let's set up a proportion.
[tex] \frac{3}{4.8} = \frac{40}{x} [/tex]
Now that we have set up a proportion we would need to cross multiply.
3*x=3x
40*4.8= 192
Solve for x
[tex] 3x=192 [/tex]
[tex] \frac{192}{3} = 64 [/tex]
Therefore, the answer would be 64.
