Question

change into seconds of 2hour 40mintues23second.​

Answer 1

Answer:

9623 seconds

Step-by-step explanation:

1 hour = 60mins = 3600 seconds

so, 2 hours = 7200 seconds. ----------- (1)

1 minute = 60 seconds

40 mins = 40 × 60 = 2400 seconds --------- (2)

and 23 seconds is also given -------- (3)

so adding (1),(2),(3) we get 7200 + 2400 + 23 = 9623 seconds.
