Last Wednesday, two friends met up after school to read the book they were both assigned in Literature class. Adam can read 1 page per minute, and he had already read 79 pages. Cody, who has a reading speed of 4 pages per minute, had read 49 pages. Eventually they had read the same number of pages. How long did that take? How many pages had each of them read?

19

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
