Question
A bird leaves its nest and travels 18 miles
per hour downwind for xx hours. On the
return trip, the bird travels 3 miles per hour
slower and has 5 miles left after xx hours.
a. What is the distance of the entire trip?
_ miles
b. How long does the entire trip take?
_ hours _ minutes & _ seconds
Let the number of hours flying downwind==H
18H ==Distance travelled downwind.
[18H - 5] / 15 ==18H/18
H == 5/3 - hours spent flying downwind
[18*5/3 - 5] / 15 + 5/15==2 - hours spent flying back to its nest.
Total distance==[5/3 * 18] * 2 ==60 miles.
5/3 + 2 == 11 / 3 ==3 hours + 40 minutes - total time spent flying back and forth.
