Answer 1

she write page in 1 hr.= 4
she write 1 page = 60/4
= 15 minutes
she write 45 pages = 45* 15
= 675min. or ( 11.25hrs.)

Answer 2

No, she will Not Complete it ,

Cause she is writing 1 page in 15 min ,

So,

45×15 =675

675 min she will need to complete The 45 pages.

BUT in 8hrs there are 480 min.

So she will be completing just 32 pages In 8hrs i.e. 480÷15= 32 Pages.
