Answer:

It will take 12 minutes

Step-by-step explanation:

We can use ratio's to solve the problem

2/3 mile 1 miles

------------ = ------------------

8 minutes x minutes

Using cross products

2/3 * x = 8*1

Multiply each side by 3/2 to isolate x

3/2 * 2/3 x = 3/2 * 8

x = 12

The required value is $2\times10^9$

Step-by-step explanation:

Weight of ants = $4\times10^{-3}$

Weight of elephant= $8\times10^6$

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

$4\times10^{-3} \times a = 8\times10^6$

We need to find a:

Solving:

$4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9$

So, the required value is $2\times10^9$
