Can you plz help me in number 6 part a and b explain how you did it plz and plz answer by 5th grade level thx

Answer: Part A: 1 hour and 45 minutes. Part B: 10:10 P.M.Step-by-step explanation: Part A We know that 1 hour has 60 minutes. Then from 7:00 P.M to 8:00 P.M there are 60 minutes. If 7:35 P.M. is 7 hours and 35 minutes, then the amount of minutes left for 8:00 P.M. is: [tex]60minutes-35minutes=25minutes[/tex] From 8:00 P.M. to 9:00 P.M there is 1 hour. And from 9:00 P.M to 9:20 P.M. there are 20 minutes. Then you have 1 hour and: [tex]25minutes+20minutes=45minutes[/tex] Therefore, How long was the movie? 1 hour and 45 minutes. Part B Knowing that Ushma got home 50 minutes after the movie ended, you need to add 50 minutes to 9:20 P.M: The amount of minutes left to 10:00 P.M. is: [tex]60minutes-20minutes=40minutes[/tex] So, here we have 40 minutes of the 50 minutes she took to got home. The remaining minutes were: [tex]50minutes-40minutes=10minutes[/tex] Then, when 40 minutes passed, the time was 10:00 P.M. And when you add 10 minutes to 10:00 P.M., you get the time: 10:10 P.M. Therefore: Ushma got home at 10:10 P.M.
