Remember that 24 hour clock time uses 4 numbers separating the hours from the minutes with a : sign.

7.35 a.m. is 07:35

7.35 p.m. is 19:35

Example

What 24 hour time is 46 minutes after 7.35 p.m.?

Answer

We start at 7.00 p.m. and then add the two minutes numbers.

35 + 46 = 81 minutes.

81 minutes is 1 hour and 21 minutes.

1 hour and 21 minutes after 7.00 p.m. is 8.21 p.m.

8.21 p.m. is 20:21 in 24 hour clock time.
