1. 10 represents the minutes to make the centerpiece, 30 represents the minutes to make the paper cranes once he gets home.
16/(q+1)=4
16/(q+1)=4 > Mult. both sides by (q+1)
16=4q+4 > Subtract 4 from both sides.
12=4q > Div. both sides by 4
q=3
Use the Pythagorean theorem:

Subtract 1764 from both sides
3136 = width^2
Take the square root of both sides
Width = 56 inches
