Mrs.Cao and Mrs.Channing were measuring their gummy worms. Mrs. Cao's gummy is 3 inches longer than Mrs.Channing's. If they line their gummy worms up end to end they measure 11 inches. How long are each of their gummy worms?
Mrs. Caos’s worm is 7 inches while Mrs. Channing’s worm is 4 inches. Think of numbers that add to 11, and then find numbers that equal to 3 (7 and 4). 7 inches - 4 inches = 3 inches. 7 inches + 4 inches = 11 inches total
