Step-by-step explanation:
1.
Let's say she starts on a Monday(first day).
She walked 10min on Monday
She then starts increasing the number of minutes each day by "2".
So
Tuesday --- 12min
Wednesday--- 14min
Thursday --- 16min
Friday --- 18min
Saturday --- 20min
Sunday ---- 22min
Total = 10 + 12 + 14 + 16 + 18 + 20 + 22
= 112minutes
She walks 112minutes in one week.
2.
Since each 8 cans are consumed per day
...
200cans would be consumed in
200/8 = 25days.
