Let n be the man's walking rate. Then:
9/n+9/27=3&1/3
243+9n=90n
243=81n
n=3
The man's walking rate was 3 mph

Answer:
2, 4, 5
Step-by-step explanation:
Answer:
h(t) = -16t2 + 144
h(1) = -16(12) + 144 = 128 ft
h(2) = -16(22) + 144 = 80 ft
h(2) - h(1) = 80 - 128 = -48 ft
It fell 48 ft between t = 1 and t = 2 seconds.
It reaches the ground when h(t) = 0
0 = -16t2 + 144
t = √(144/16) s = 3s
It reaches the ground 3s after being dropped.
