A bird leaves his nest and travels 20 miles per hour downward for x hours. On the return trip the bird travels 4 miles per hour slower and has six miles left after x hours. What is the distance of the entire trip? How long does the entire trip take

Answer 1

d = 20mi/h * xh = 20x miles.

d = (20-4)mi/h * xh + 6 = 20x
16x + 6 = 20x, X = 1.5 Hours.

d = 20 * 1.5 = 30 Miles from nest.

Dt = 2 * 30 = 60 Miles. = Total distance traveled.

d = V*t = 30, 20*t1 = 30, t1 = 1.5 Hours.

16*t2 = 30, t2 = 1.875 Hours.

t1+t2 = 1.50 + 1.875 = 3.375 Hours.
