Part B: How much time does Melvin spend swimming every day? Show your work.

Part C: Is it possible for Melvin to have spent 70 minutes playing tennis if he plays and swims for a total of exactly 110 minutes and plays tennis for 40 minutes longer than he swims? Explain your reasoning.

Answer 1

Answer 2
