Question

Morris hated raking leaves. There were two trees that he hated the most, because they always were dropping leaves. One day he decided to count how many red and yellow leaves dropped from the trees every hour. In the first hour there were 8 red leaves and 8 yellow leaves on the ground. In thesecond hour there were 12 yellow leaves and 15 red leaves on the ground. In the third hour he counted 15 yellow leaves and 16 red leaves on the ground. In the fourth hour there were 19 yellow leaves and 23 red leaves on the ground. Then at the end of the fifth hour he found 22 yellow leaves and 24 red leaves on the ground. If the leaves kept dropping at the same rate, how many hours would it take for 50 red leaves and 50 yellow leaves to drop on the ground?

Answer 1

Hi Jasjjz,

you have to follow the pattern here:

red leaves: 8,15,16,23,24........

+7,+1,+7,+1 this is a pattern- if you continue you’ll get

8,15,16,23,24, 31,32,39,40,47,48,55

12 hours

similarly for yellow leaves the pattern is +4,+3,+4,+3,...

8,12,15,19,22,26,29,33,36,40,43,47,50

13 hours
