This is Geometric progression with

$\left \{ {{u_1=1,\: u_2 =2} \atop {u_n=2^{n-1}u_1} \right.$

Then the fomular of sum is

$S=u_1\frac{2^n-1}{2-1} =1\times(2^n-1)=2^n-1\\To\: save\: 1 \:million\: then \; our \:sum \: will \: be\: 1000000\\Hence,\\2^n-1=1000000\\2^n=1000001\\n=log_{2}{1000001}\approx19,9\\Thus, it\:would \;be \:19 \:months \:before\: we\: saved \:1000000 \:pounds$

Answer:

46 cm

Step-by-step explanation:

Let p represent the length in cm of 1 bap'ai; let k represent the length in cm of 1 bok'ai. Then we have ...

12p +2k = 100

10p +10k = 100

Subtracting the second equation from 5 times the first, we get ...

5(12p +2k) -(10p +10k) = 5(100) -(100)

50p = 400

p = 8 . . . . cm

Then the second equation tells us ...

10(8) +10k = 100

10k = 20

k = 2 . . . . cm

Then 5p+3k = 5(8) +3(2) = 46 cm.

The distance 5 bap'ai and 3 bok'ai is 46 cm.
