A concert starts at 4:30 pm. and ended at 6:15 pm. how long was the concert?

Answer 1

hey mate

for finding out how long was the concert

substract the greater value from smaller value

6:15-4:30

convert into minutes
=>(6×60+15)-(4×60+30)
375-270
=105

the concert went for an hour and 45 mintues

hope it helps
