Question 1102071
A bird leaves its nest and travels 20 miles per hour downwind for x hours.
 On the return trip, the bird travels 4 miles per hour slower and has 6 miles left after x hours.
:
 A) What is the distance of the entire trip
dist = speed * time
d = 20x + 16x + 6
d = 36x + 6 miles
:
 B) How long does the entire trip take? 
time = dist/speed
t = 2x + {{{6/16}}}
t = 2x + {{{3/8}}} hrs
