If the grid and tanya start typing at the same time, tanya have typed 14.67 pages.
A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.
Now it is given that,
Pages typed by Ingrid = 3
Pages typed by Tanya = 4
So, the ratio of pages, Ingrid : Tanya = 3 : 4
So, If the grid and tanya start typing at the same time Ingrid has typed 11 pages
Thus, dividing the ratio be 3 we get,
3 : 4 = 1 : 1.33
Now for 11 pages multiplying 1.33 with 11 we get,
1.33 x 11 = 14.67
