pages in 2 hours, Lucille types 8 1/2 pages in 3 hours, and Pauline types 9 pages in 3 hours. Who
is the slowest typist?
O o. Ann
O g. Pauline
Op. Mary
Ok Lucille
b. Rose​

Answer 1

Answer:

Rose types slowest among all the persons.

Step-by-step explanation:

Given,

Mary types ten and a half pages in three and a half hours.

Ann types seven and a half pages in two and a half hours.

Rose types five and a half pages in two hours.

Lucille types eight and a half pages in three hours.

And Pauline types nine pages in three hours.

To find,

Who is the slowest typist?

Calculation,

→ The speed at which Mary types is:

speed of typing = no. of pages/time taken

speed of typing = $\frac{10\frac{1}{2} }{3\frac{1}{2} }$ = 21/7 = 3 pages/hour.

→ The speed at which Ann types is:

speed of typing = no. of pages/time taken

speed of typing = $\frac{7\frac{1}{2} }{2\frac{1}{2} }$ = 15/5 = 3 pages/hour.

→ The speed at which Rose types is:

speed of typing = no. of pages/time taken

speed of typing = $\frac{5\frac{1}{2} }{2}$ = 11/4 = 2.75 pages/hour.

→ The speed at which Lucille types is:

speed of typing = no. of pages/time taken

speed of typing = $\frac{8\frac{1}{2} }{3 }$ = 17/6 = 2.833 pages/hour.

→ The speed at which Pauline types is:

speed of typing = no. of pages/time taken

speed of typing = $\frac{9}{3}$ = 3/1 = 3 pages/hour.

Therefore, Rose types slowest among all the persons.
