Question

39 feet × (1 yard / 3 feet) × (1 min / 60 sec)

a) 0.2167
b) 0.78
c) 0.65
d) 0.585

Answer 1

The solution involves converting feet to yards and then converting seconds to minutes, yielding an answer of 0.2167 yd/min, which corresponds to option (a) 0.2167.

Step-by-step explanation:

To solve the question 39 feet × (1 yard / 3 feet) × (1 min / 60 sec), we need to perform unit conversion and multiplication.

First, we convert feet to yards using the conversion factor 1 yard = 3 feet. When we multiply 39 feet by the conversion factor (1 yard / 3 feet), the feet units cancel each other out:

39 ft × (1 yd / 3 ft) = 13 yd

Next, we convert seconds to minutes using the conversion factor 1 minute = 60 seconds. Thus, multiplying by (1 min / 60 sec) converts seconds into minutes:

13 yd × (1 min / 60 sec) = 0.2167 yd/min

So, the correct answer is 0.2167 yd/min, which matches with option (a) 0.2167.
