Explanation for Question 37 From the Math (Calc) Section on the Official Sat Practice Test 10
Now for number 37, we're told that a paragraph Falcon can reach speeds 2 of up to 200 miles per hour while dry, 3 while driving diving to catch prey. 4 And so it's the fastest animal went and dive that says that the paragraph 5 Falcons minimum speed, what is the maximum speed in feet per second 6 in feet per second? So this is really a conversion question, 7 right? Because we're told that we're, we can go miles per hour, 8 200 miles per hour, and they want us to change that to feet per 9 second. So first let's focus on the numerator. 10 We want to get from miles to feet. So I'm going to multiply by 11 conversion factor that will allow me to cancel out the miles. 12 Right. And I see that right here. I know one mile is five to 13 eight, zero feet, right? So you see if I were to multiply cross these 14 miles, I have one in the numerator and one in the denominator. 15 So they would cancel each other out. And that means that I've successfully introduced 16 feet into the equation. So we're close now, 17 but remember I want, um, feet per second. 18 And right now I have hours happening down here. 19 So what I need to do is take that hours and convert it to 20 seconds right now I know that one hour is 60 minutes. 21 So this would allow me to cancel out my hours and leave me with 22 with minutes. But what I want is seconds, 23 right? I know that one minute here has 60 seconds and now allow 24 this to change. Essentially, whichever unit you're trying to get out of your equation, 25 hour...
