dumb question
1. Iris has found some dinosaur bones and a fossil footprint. The length of the footprint is 40 cm, the length of the thigh bone is 100 cm, and the length of the body is 700 cm.
A. Iris found a new track that she believes was made by the same species of dinosaur. If the footprint is 30 cm long and if the same ratio of foot length to body length holds, how long is the dinosaur?
