Dana can type nearly 90 words per minute. Use this information to find the number of hours it will take her to type 2.6 x 105 wo
Vlad1618 [11]

Dana can type 90 words per minute.

Since, 1 minute = \frac{1}{60} hours

Therefore, number of words she can type = \frac{90}{\frac{1}{60}}

                                                                      = 90×60

                                                                      = 5400 words per hour

If she types 2.6\times 10^5 words in 'x' hours.

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= 5400\times x

Therefore, 5400\times x =2.6\times 10^5

5400x=260000

x=\frac{260000}{5400}

x=48.15 hours

Therefore, Dana types 2.6\times 10^5 words in 48.15 hours.
