42
remainder. 40
2 minutes

Step 4: Convert the remainder 2 minutes into seconds and add 40 seconds

Step 5: Divide 160 seconds by 32 seconds

5. Write 32 seconds as 5 160 seconds
quotient. 15
Thus, 16 hours 32 minutes 10
40 seconds ÷ 5 = 3 hours 10
18 minutes 32 seconds. 0 seconds

Days hours minutes
7 8 15 12
– 7
1 day

5 hours
7 39 hours
– 35
4 hours + 12 minutes (4 × 60 = 240 + 12 = 252 minutes)

= 252 minutes
36 minutes
7 252 minutes
