Ok so... W is week. It would be 20+2w. Because we start with the plants hight (20) and them it grows two cm per week, so 2w.
7/4 miles in 11 minutes
x miles in 1 minute
Cross multiply we will get:
7/4 = 11x
7/4 x 1/11 = x
7/44 = x
So 7/44 miles per minute is the answer
I have finished doing my calculations and i think my answer may be correct but i got 6
