I believe the answer is <span>D) 15 yards per second
</span>
let's convert all of them into meter/hour
2 meters/minute = 120 meter/hour
6 miles/hour = 6x1609.34/hour = 9656.06 meter/hour
10 feet per second = 36000feet/hour = 1097.28 meter/hour
15 yards per second = 54000 yards /hour = 49377.6 metr/hour >>>> Fastest
1.4/5
2.5/6
3.4 7/9
4.1/2
5. 5/12
6. 3 1/7
7. 12/35

Answer:
b = 2(g + r)
Marisa used b = 8 cups of blueberries.
Step-by-step explanation:
Let g be the cups of green grapes, r be the cups of red grapes, and b be the cups o blueberries Marisa used..
then we know that
g = 1 (Marisa used 1 cup of green grapes)
r = 3 (Marisa used 3 cup of red grapes)
g + r = 4
Marisa used twice as may cups of blueberries as cups of grapes; this means
b = 2(g + r )
b = 2(4) = 8
Marisa used 8 cups pf blueberries.
I could be wrong but I think it’s 144,000m for the area
