Let the weight of the first truck be represented by w.
total weight = w + (2 + w) + (2 + 2 + w) + (2 + 2 + 2 + w)
32 = 4w + 12
20 = 4w
w = 5
Therefore, the first truck weighs 5 tons, the second weighs 7 tons, the third weighs 9 tons and the fourth weighs 11 tons.
Diversification is putting more money into more then one investment
If she read 20 in half an hour how many can she read in 1 hour=40
so, that gets you 120 the answer is she can read 120 pages in 3 hours
