Question

26. The first half of a play is 35 minutes longer than the second half of the play. If

Answer 1

155-35= 120 (you subtract 35 so you get the number if both plays lasted the same time )
120/2= 60 (you get the amount of time one play lasted without extra 35 minutes)
60+35=95 (then add 35 minutes to one play because 1 one is longer than the other one)

the first half of the play is 95 minutes long.
