A:
Answer:i say 40 minutesStep-by-step explanation: in the first 4 minutes she planted 7 flowers, in the next 8 minutes she planted 21 flower. so what i did was divide 70 by 7... since the amount of flowers is going up by 7's. so 70 divided by 7 is 10... now every 4 minutes you plant flowers so 10 by 4= 40 minutes
