Every mile is 5,280 feet, so all you have to do is use this equation. 5,280 * 2.5
= 394 R 1
= 394 1/3
1183 divided by 3 equals
394 with a remainder of 1
The correct answer is B. 8 + 8 + 8 + 8, OR 4*8
<span>Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go, AND HE STOPS 8 TIMES, SO correct answer is 8*4 = 32 </span>
Try this solution:
1. Note, that 9*0.1=0.9; 0.9*0.1=0.09; 0.09*0.1=0.009, etc.
It means, the gives series is geometric sequence, where a₁=9, q=0.1.
2. Using a₁=9 and q=0,1 it is possible to calculate the sum of this sequence:

answer: 10
