Clark left to school at 7: 43a. m. he got to school 36 minutes later. at which time did clark get to school?

Clark got to school at 8:19 am. 36 minutes can be split up into 6 minutes and 30 minutes. Six minutes after 7:43 am is 7:49 am. Thirty minutes after 7:49 am is 8:19 am.

If he left at 7:43 am he was 17 minutes from 8:00 (subtracting 43 from 60) 36 min less 17= 19 therefore arrived at 8:19 am
