\frac{7527}{3424 \times 24.57} = \frac{5454}{2481 \times x}
1. Calculate the left side of the equation:
\frac{7527}{3424 \times24.57}\approx0.0941
2. Set the left side equal to the right side:
0.0941=\frac{5454}{2481 \times x}
3. Solve for x :
x=\frac{5454}{2481\times0.0941}\approx23.35
So, approximately 23.35 hours will be needed to distribute 5454 letters to 2481 households.
