jonny [76]

Answer:

$N_{a} = T_{a}$

$N_{c} = 2 \times T_{c}$

Step-by-step explanation:

Alejandro has read 28 pages so far and he can read 1 page per minute.

Again, Carly has read 12 pages so far and he can read 2 pages per minute.

If the variable N represents the number of pages read by the readers and T in minutes represents the time spent by the reader to read this number of pages, then

For Alejandro: $N_{a} = 1 \times T_{a} = T_{a}$ ......... (1)

For Carly: $N_{c} = 2 \times T_{c}$ .......... (2)

So, the equations (1) and (2) gives the number of pages that Alejandro and Carly read. (Answer)
