We know that in one minute the toddler is 2(270)=540 feet and mother is 580 so less than 1 minute
3+3= 6
6+1= 7 is your answer
1) The ratio of used books to all books is 6:14
2) The ratio of used books to new books is 6:8
Multiply 40x7 then subtract that total you got from multiplying 40x7 with 420
40x7=160
420-160=260
260 pieces of wood were left.
I’m pretty sure it would be just E and F
