Question

3 \\(\frac{47 \text{ feet}}{60 \text{ seconds}} = \frac{?}{45 \text{ seconds}}\\)
decimal answer.

Explanation:

Step1: Let the unknown be \( x \). The proportion is \( \frac{47}{60}=\frac{x}{45} \).

Step2: Cross - multiply to get \( 60x = 47\times45 \).

Step3: Calculate \( 47\times45 = 2115 \). Then \( x=\frac{2115}{60} \).

Step4: Simplify \( \frac{2115}{60}=35.25 \).

Answer:

35.25
