Question 176494: In a tall office building, one elevator leaves the third floor and ascends at a speed of 2 floors per second. Another elevator leaves the 59th floor at exactly the same moment and descends at a speed of 2 floors per second. If the two elevators do not stop, how long will it take them to pass each other? At what floor will the elvators pass each other?
I can solve this problem by subtracting 3 from 59 to get a distance of 56 floors. Since they are traveling at the same rate divide this by 2 and get 23 floors. So they would pass at the 26th floor. 23 floors at 2 floors per second would be 11.5 seconds.
My problem is that I can do all this logically but my teacher wants an equation with variables! Not sure how to do that. Thanks for any help!

Question 176536: It take Felicia 25 minutes to walk one mile. At this rate, how long would it take her to walk 7 miles?
I multiplied 25 x 7 = 175 minutes. But am confused trying to use the formula.
D=RT
D=7 miles, R=25 min/mile, T=T
7=25T
7/25 = T
T= .28 minutes
What am I not understanding? Thanks for your help!

Question 176994: The path of a falling object is given by the function s=-16t^+v0t+s0 where the v0 represents the initial velocity in ft/sec ans s0represents the initial height. The variable t is time in seconds, and s is the height of the object in feet. if a rock is thrown upward with the initial velocity of 32 feet per secound from the top of a 40 foot building a) write the height equation b)how high is the rock after 5.0 seconds,after how many seconds will the rock reach maximum height and what is the height?
I have been stuck on this problem for days I do not know where it is from it is a problem given by our teacher and I have no clue where it is from and that is the truth.
