Question

iv) Calculate the total time:
17 minutes 45 seconds and 18minutes 23 seconds.​

Answer 1

Answer:

First, we have to convert minutes into seconds and then we can calculate.

1 min = 60 sec

17 min = 17 x 60 sec = 1020 sec + 45 sec = 1065 sec

18 min = 18 x 60 sec = 1080 sec + 23 sec = 1103 sec

Total time = 1065 + 1103 sec = 2168 sec = 36 minutes and 7 seconds.
