17 years
Step-by-step explanation:
1200/3z = 8
400=8/3 year for each building
they take 8
1600 is 2/3 year for each building
2/3 times 25 is 16.666
Miles driven per hour is 60 miles per hour
Hours driven per mile is 0.01667 hours per mile
<em><u>Solution:</u></em>
Given that,
On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours
Therefore,
Miles driven = 210 miles

To find: miles driven per hour and the hours driven per mile
<h3><u>Miles driven per hour</u></h3>

<h3><u>Hours driven per mile</u></h3>

Thus both the miles driven per hour and the hours driven per mile are found
A(n) = –3 • 2⁽ⁿ⁻¹⁾
for n = 1 , A₁ = -3.(2)⁰ = -3
for n = 2 , A₂ = -3.(2)¹ = -6
for n = 3 , A₃ = -3.(2)² = -12
for n = 4 , A₄ = -3.(2)³ = -24
...........................................
for n = 8 , A₈ = -3.(2)⁷ = -384
