Answer:
6/5 hr, or 1 hr 12 min
Step-by-step explanation:
We're looking for the time required for two people to clear a field.
We'll end up with an expression that looks like:
1 job
------------ = time
rate
or
1 job
------------- this has dimensions of time (hr).
1 job/hr
specifically, we evaluate the following expression:
1 job
--------------------------------
1 job 1 job
-------- + --------
3 hr 2 hr
This simplifies to
1 1
-------------- = ----------- = 6/5 hr, or 1 hr 12 min
1/3 + 1/2 5/6
The speed is the change of distance over the change of time.
s = (d - d1)/(t - t1)
where the subscript 1 indicates as "initials."
The initial time starts at zero. So,
s = (7000 - 10000)/(15 - 0) = -200 feet (elevation) per minute
The value is negative because the hang glider flew downward.
Is there a picture with this?
