Question

One afternoon your family goes out to pick strawberries for jam. At 1 pm, have picked 3 quarts. You finish picking at 3 pm and have 28 quarts of strawberries. At what average rate was you family picking?

Answer 1

You can think of this problem in terms of slope of a line that goes through the points (1,3) and (3,28).

(28-3)/(3-1) = 25/2 = 12.5

Answer 2

assuming they started from 12 noon ...

at 1pm rate is 3qt per hr.

at 3pm rate is (28-3)/2 = 12.5 qt per hr.

(3 + 12.5)/2 = 7.75 qt per hr.

Answer 3

28-3= 25 now there are 2 hours left so 25/2 = 12.5. Average = 28/3hours=9.3333. your family picked an average of 9.3 an hour

Answer 4

ok 28-3 = 25

tiem 3-1 = 2 hrs

so in 2 hrs picked 25quarts

so i 1 hr = 12.5quarts

thats yr averate rate
