time taken to prepared strawberry pie = 20 minutes & 30 second
time taken to baked = 45 minutes
time taken in whole procedure = ?
we can solve it by different method first we change total time period in same unit (like minutes change in seconds) and then add all time to b taken on it. In second method we can solve it by using decimal for second (like 20.30 minutes) and add them.
Now we solve it with simplest method :-
Time taken in whole procedure = 20.30 minutes + 45 minutes
Time taken in whole procedure = 65 .30 minutes
we can convert it in seconds if required 65.30 x 60 = 3918 seconds
