Two window washers start at the heights shown. (a: 21 ft high rising 8 in per second. the other is 50 feet high descending 11inches per second) one is rising one is descending. how long does it take for the two window washers to reach the same height? explain

For this case, the we have that the generic equation of motion is:

We have then:

Where,

First equation:

Second equation:

For same height we have:

Clearing time:

 it takes 18.31s for the two window washers to reach the same height
