A. 850 feet
B. 8.5 feet
C. 8500 feet
,D. 85 feet - CORRECT ANSWER: A. 850 feet
(A) Total distance = size of step x number of steps
D = 0.0000002 x 4,250,000,000
D = (2 x 10-7) x (4.25 x 109)
D = (2 x 4.25) x (10-7 x 109)
D = (8.50) x (102)
D = 8.5 x 100
D = 850 feet

, B. 100 morning, 260 afternoon
C. 110 morning, 250 afternoon
D. 140 morning, 220 afternoon - CORRECT ANSWER: A. 120 morning, 240 afternoon
(A) The number of oranges picked in the morning equal X and the number picked in the
afternoon equals 2X. Their sum x + 2x = 3x is the total number of oranges that were
picked. So, 3x = 360; x = 360/3; x = 120. Thus, in the morning the farmer picked 120
oranges, and in the afternoon 240 oranges.
