Answer 2

Answer:

a) 1 minute = 60 seconds

15 minutes = 15×60 = 900 seconds

900+50 = 950 seconds

3 minutes = 3× 60 = 180 seconds

180 + 45 = 225 seconds

950-225 = 725 seconds

ANSWER = 7 minutes 25 seconds

OR

725 seconds

b) 1 year = 12 months

16 years = 16×12 = 192 months

6 years = 6×12 = 72 months

72+4 = 76 months

192-76 = 116 months

ANSWER = 9 years 6 months

OR

116 months
