Question

Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 2.5x10 to the 5th power

Answer 1

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 2

104.17 hours.

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
`2.5* 10^(5)` words.

To find number of hours, we will divide
`2.5* 10^(5)` by 40 as:

`(2.5* 10^(5))/(40)`

`(2.5* 10^(5))/(4* 10)`

`(2.5* 100000)/(40)`

`(250,000)/(40)`

`6250`

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

`(6250)/(60)=104.166\approx 104.17`

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