Good day pupils and students, in this lesson you will know how to change/convert any given minutes of time to its seconds. if you are writing common entrance examination this year, make sure you pay attention very well.
The concepts concerning this is simple to understand, but attention is needed. we all know how clock makes its movements and the mechanism involved, i mean seconds, minutes and hours rotational. These three rotational operators make a completes time frame of our daily activities. Now lets compare them and see their changes.
When ever you're asked to change minutes to a particular seconds or from seconds to minutes, you must consider one thing, which is:
60 seconds = 1 minute
60 minutes make 1 hour
That means, 2 min = 120s ( S means second)
2min to seconds ( M = minute)
1 x 60s = 60s
2 x 60s = 120s
Typical example,lets change 60 min to seconds
1min = 60s
then, 60 x 60 = 3600s
therefore 60min = 3600s
Knowledge: Just multiply any given Minutes by 60s and you're good to go...
Examples 1
Change the following time to seconds
a. 32 min to seconds.
b. 1 min to seconds.
e. 130 min to seconds
Solution
Working
Without calculator you can do it this way:
(1) 3 2 0
+ 3 2 0
+ 3 2 0
+ 3 2 0
+ 3 2 0
+ 3 2 0
-------------------
19 2 0
-----------------------
36 in 6 places and 0 to each.
there 32 min is = 19 2 0s
b. 1 min to seconds.
1 min = 60s
there 1 min = 60s .
e. 130 min to seconds
1 min = 60s
2 min x 60 = 120 s
then 130 x 60 = 7, 800 seconds
therefore e. 130 min = 7, 800 seconds
When ever you're asked to change min to sec, always begin with 1min = 60 sec, then multiply the given minute by 60 that all.
Now do these
Change the following minutes to seconds
1. 3 min
2. 57 min
3. 120 min
4. 60 min
5.22 min
