sec
we know , 1 min =60 sec 100 sec =1 min 40 sec
327 seconds.
11 minutes and 15 seconds
Three numbers between 21 seconds and 22 seconds are 21.1 sec, 21.2 sec, and 21.3 sec
13 seconds/1 minute = 13 sec/60 sec = 13/60
27 seconds.
10 Min's - 5 Min's = 5 Min's - 50 Sec's = 4 Min's 10 Sec's - 15 Sec's = 3 Min's 55 Sec's 3 Minutes and 55 Seconds. ------------------- Interesting math, but the correct answer is still 4 minutes, 25 seconds. Why did you subtract the 15 seconds instead of adding it??
10 sec/1 min = 10 sec/60 sec = 1/6
4 sec/1 min = 4 sec/60 sec = 1/15
604,800 seconds
