Answer:
The answer to your question is a) 4/12 b) 5/12
Step-by-step explanation:
Data
Lettuce = 1/12
Carrots = 3/12
Corn = 4/12
Red radishes = ?
a)
The total of the garden is 12/12
Red radishes = 12/12 - 1/12 - 3/12 - 4/12
= 12/12 - 8/12
= 4/12
4/12 of the garden are red radishes.
b)
Corn of lettuce = 1/12 + 4/12
= 5/12
5/12 of the garden are corn or lettuce.
Let n = minutes since 12:00 pm when Malory catches up to Dori.
Dori travels
(50 steps/min)*(n minutes) = 50n steps
Malory begins walking at 12:20 pm, so she walks for (n - 20) minutes. She travels
(90 steps/min)*(n - 20 min) = 90n - 1800 steps
Equate the steps traveled by Dori and Malory.
90n - 1800 = 50n
40n = 1800
n = 45 min
The time corresponding to n = 45 min is 12:45 pm
Answer: 12:45 pm
