he tennis match ended at 5:10 P. M. and took 55 minutes to complete. What time did the tennis match start

4:15 P. M. good luck!

4:15 P. M. you can think about this logically and not just mathematically. What I mean by this is that the tennis match was almost an hour long so it didn't quite start at 4:10, but if you add 5 min to 4:10 you get 4:15 P. M.
