1 h = 60 min
0.9 h = 54 min
1.9 h = 1 h 54 min
1 h = 60 min
write 5 h 05 min like :
5 h 05 min = 4 h + 60 min + 5 min = 4 h 65 min
5 h 05 min - 1.9 h = 4 h 65 min - 1 h 54 min = 3 h 11 min PM
PLEASE EXPLAIN. I DO NOT GET IT!!!!!!!!!HOW DO YOU CALCULATE THIS?
5:05 PM SUBTRACT 1.9 HOURS?

0.9 h = 0.9 * 60 min = 54 min
Change 1.9 hours into a form we can use.
Let's break it into two parts. We know 1 hour is easy enough, and that will change the time to 4:05 PM (Subtract 1 hour from 5:05 PM).
For the 0.9 hour part, let's change this to minutes.
(0.9 hours)*(60 min / 1 hr) = 54 minutes.
Since we are at 4:05 PM, subtract 5 of the 54 min and we are at 4:00 PM and now need to subtract the remaining 49min, which 3:11 PM.
So 5:05 PM subtracting 1.9 hours is 3:11 PM. They key to this problem is getting the 1.9 hours into something we can use, and to break the large problem into smaller, managable problems.
