10 to the 5th power is 100,000.

So, 2.5 x 100,000 = 250,000

Since Samuel can type 40 words per minute, do 250,000 ÷ 40 = 6250

Since there are 60 minutes in an hour and Samuel types 40 words per minute, multiply 40 x 60 until you get close to 6250.

Answer:

104.17 hours.

Step-by-step explanation:

We have been given that Samuel can type nearly 40 words per minute. We are asked to find time taken by Samuel to type [tex]2.5\times 10^{5}[/tex] words.

To find number of hours, we will divide [tex]2.5\times 10^{5}[/tex] by 40 as:

[tex]\frac{2.5\times 10^{5}}{40}[/tex]

[tex]\frac{2.5\times 10^{5}}{4\times 10}[/tex]

[tex]\frac{2.5\times 100000}{40}[/tex]

[tex]\frac{250,000}{40}[/tex]

[tex]6250[/tex]

Now, we will convert 6250 minutes to hours by dividing 6250 by 60 as 1 hour equals 60 minutes.

[tex]\frac{6250}{60}=104.166\approx 104.17[/tex]

Therefore, it will take 104.17 hours to type the given words.
