Dana can type 90 words per minute.
Since, 1 minute =
hours
Therefore, number of words she can type = ![\frac{90}{\frac{1}{60}}](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B%5Cfrac%7B1%7D%7B60%7D%7D)
= 90×60
= 5400 words per hour
If she types
words in 'x' hours.
Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time
= ![5400\times x](https://tex.z-dn.net/?f=5400%5Ctimes%20x)
Therefore, ![5400\times x =2.6\times 10^5](https://tex.z-dn.net/?f=5400%5Ctimes%20x%20%3D2.6%5Ctimes%2010%5E5)
![5400x=260000](https://tex.z-dn.net/?f=5400x%3D260000)
![x=\frac{260000}{5400}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B260000%7D%7B5400%7D)
hours
Therefore, Dana types
