The units you want is \frac{bolts}{min}, so you set up the following equation:
\frac{440\ bolts}{48\ mins} = \frac{x}{30\ mins} \\
440*30=48*x\\
13200=48x\\
x=\frac{13200}{48}=275 \frac{bolts}{min}

The distance between two locations, A and B, is calculated using a third location C at a distance of 15 miles from location B. I
Jobisdone [24]
We will first calculate ∠A:
∠∠A = 180° - ( 105° + 20 ° ) = 180° - 125° = 55°
Then we will use the Sine Law:
15 / sin 55° = AB / sin 20°
15 / 0.81915 = AB / 0.342
AB · 0.81915 = 15 · 0.342
AB · 0.81915 = 5.13
AB = 5.13 : 0.81915
AB = 6.26 ≈ 6.3 miles
Answer: The distance between the locations A and B is 6.3 miles.
