<p>I think I have seen threads like this before regarding SAT questions so I guess I can start one for November SAT. Ask questions you want answered and everyone should try to answer the ones you know that way we can get a better idea on what we got.
Here's one I can answer: Math
You are going one way 40mph and coming back 60mph what is your average speed. You would think it was 50 but that's wrong because you are going 40mph at a longer amount of time than 60mph so it isn't even. So I took a random number of miles (240) found out how long it takes to go at the different speeds (40mph:6hours 60mph:4hours) added that together (4+6=10) than took 10 hours divided that by 2 (you are only supposed to find the mph or one way not 2) and did 240/5=48.</p>
<p>The faster way to approach that would be:</p>
<p>40 x 60= 2400</p>
<p>2400 x 2= 4800</p>
<p>4800/40+60 = 48. </p>
<p>Took me about 15 seconds for that today. Considering it was supposed to be a difficult question.</p>
<p>There was a math question that had a regular hexagon with a square or something in it and you had to find the slope that went through A and D. </p>
<p>Did the slope make a 30, 60, 90 triangle? Forgot what I put as an answer…1 I think?</p>
<p>Also, was the math section w/ number 19 as something like x=1234567891011…99100 an experimental section?</p>
<p>@darkrum lol what are you talking about? I had an experimental math too.
And for OP’s question, you can use dimensional analysis:
Let x represent the distance (in miles) from point A to B.
Time to move to point B from A:
x miles * (1 hour/40 miles) = x/40 hours
From B to A:
x miles * (1 hours/60 miles) = x/60 hours
Average speed: total distance/total time. Total distance: 2x (since each way is x miles).
So we have:
2x/(x/40+x/60)=2/(1/40+1/60)=48 miles/hour</p>
<p>Math was definitely experimental I had an extra math. There was one crazy math section where I left 3 blank so I am hoping it’s that.</p>
<p>what did people get for the two tangent circles one radii 4 and 5, maximum distance</p>
<p>and what are the possible remainders when an integers is divided by 5</p>
<p>possible remainders are [0,1,2,3,4]. 5/5=0 6/5=1 REMAINDER 1 7/5=1 REMAINDER 2 8/5=1 REMAINDER 3 9/5=1 REMAINDER 4 10/5=2 REMAINDER 0 AGAIN. so it goes in that cycle no matter what numbers you use.</p>
<p>For the distance one I got 18. The furthest parts of a circle are the two endpoints of a diameter so the diameter of one is 8 and the diameter of another is 10 and if they are directly next to each other you can add the diameters and get 18.</p>
<p>the one with f(x)-1, how many points does the graph hit the x axis
one with the finding r in a parallelogram? trapezoid?</p>
<p>finding angle ACB with the central angle 55</p>
<p>writing question</p>
<p>improving sentences: one about the tomb with the new entrance
error i.d. one about the space director and her 950 hrs of four space flights, one about the cook placing sliced fruit on the bottom</p>
<p>the free response with the tokens question. it was like, 5 small tokens and 5 large tokens, the small had a value of 1/4 and you needed to find the individual value of the large token, it was 7/8 correct? I put 1.75 though.</p>
<p>i put 4 since at y=1 the function intersected 4 times, so if you move one down, it will 4 times on the x axis</p>
<p>Im telling you, it’s an average if 1.4 pencils !!!</p>
<p>@cello96 18 for circles, remainders {0, 1, 2, 3, 4}, f(x)-1 hits it 4 times (you just see where f(x) intersects x=1). Don’t remember what that trapezoid thing was.
@cryptogamics You’re right, it’s 1.75.
@Diluvio lol what are you talking about.
Guys, this is a heinous crime. You’re not supposed to discuss test materials till Wednesday.</p>
