This question needs more information
1 foot = 12 inches
12 * 5 = 60 and 8 * 12 = 96
Therefore, 60 inches is a shorter length than 8 feet.
im quite positive that the x-intercept is 1,6
LiftA= u m/s ( upwards)
LiftB= -u m/s(downward)
Velocity A relative to B= V lift A- V lift B=8m/s
u-(-u)=8
u=4m/s
Lift A= 4 m/sec
Lift B= -4m/sec
For someone standing on first floor will be stationary W.r.t to the lift.
V lift A relative to Man= V liftA - V man= 4m/s
V lift B relative to Man= V lift B- V Man= -4 m/s
(-4/5) / 3 =
-4/5 * 1/3 =
-4/15 mile per minute
