hmm. somewhere around 342miles per hour? i cant think of an answer for the first one
butter? bread?
How did you work that out ? (plane one)
Butter, bread. NO.
well the plane takes 2 trips correct? so total will be 2400miles.
so first journey was like 400mm/hour, second one was 300m/hour.
so i get 700.
2400 over 700 X 100 = 342.
