Superguy is flying at treetop level near Paris when he sees the Eiffel Tower elevator start to fall (the cable snapped). His xray vision tells him Lois LaTour is inside. If Superguy is 1.00 km away from the tower, and the elevator falls from a height of 122.5 m, how long does Superguy have to save Lois, and what must be his average speed?
A) 3.00 s, 333 m/s
B) 5.00 s, 200 m/s
C) 7.00 s, 143 m/s
D) 9.00 s, 111 m/s
E) 10.0 s, 96.0 m/s

Have you calculated how long it takes the elevator to free fall 122.5 m? That would be a good way to start.
Once you have calculated that time T, the speed required is easy: 1000m/T
One of the choices fits perfectly 
I am really not good at physics. How would I go about finding how long it takes the elevator to fall?
Is it going to have something to do with 9.8m/s? 
H = (1/2)g T^2, so
T = sqrt(2H/g) is the time to fall
yes, it has something to do with g.
People aren't "good at physics" until they try solving the problems. 
H=1/2gt^2
t=sqrt(2h/g)
=sqrt(2*240/9.8)
=6.99sec
speed=d/t
=1000/7
=142.8m/s
