First we will calculate rate of work of rosa and amy.
work done by rosa in time t=t*1/7
Work done by Amy and rosa=t(1/7+1/4.2)
t/7+t/a=t/4.2
t=10.5 hr
Always keep remember those formula or logic belowWork rate × Time to finish the job = 1 job done
Work rate = (1 job done) / (Time to finish the job)
Time of doing the job = (1 job done) / (Work rate)
So add them together
100+132.5=232.5 kg
kilograms=1000 grams so
232.5kg=1000 times 232.5 grams
232500 grams
I'm afraid you're wrong. We may divide 24 by 8 to find out how long does it take for Alejandra to husk 1 ear of corn and then just divide 33 by the result:
24 ÷ 8 = 3
So Alejandra husks 1 ear of corn in 3 minutes.
33 ÷ 3 = 11
Answer: In 33 minutes Alejandra can husk <u>11 ears of corn</u>.
