Answer:
4:50 hrs to school activities
Step-by-step explanation:
the entire school day 6:10 hrs (with breaks)
so if we remove the breaks (which are 1:20hrs in total) we'll have 4:50hrs.
the equation would be: (the time the full day is)-(the total of breaks)= the school activity time.
so: 6:10hrs-1:20hrs= 4:50hrs
there's your answer. 4:50 hrs
*just remember i am working in the hrs format meaning 60 mins= 1hrs*
