What is the speed of sound in dry air if th e temperature is 46°c?

i'm just gonna leave this comment here, so i can get a challange done-

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
