A watch loses five seconds every one hour How many minutes will it loss in two days
1 day=24 hours
2 days=48 hours
If it loses 5seconds every hour then in 48hours it will lose
In 2days,it loses 4minutes
good work, but if you are going to include the units in your expressions, it is important to be careful with them:
48hours x 5seconds=240 hour-seconds
what you need to do is make sure that the units cancel properly.
48hr x 5s/hr = 240s
