Since an hour is 60 minutes, 75 minutes would be an hour and a quarter.
OK, so I need to figure out how many hours there are in 75 minutes. Now, I know I'm just guessing this answer but I'm guessing it's 2 hours and 50 minutes but I'm not 100% sure. Cacao and thank you?
75/60=1.25 hours
Well, if you are living on earth and remain here, I'd say that the there is one hour in 75 minutes, with 15 minutes "left over."
If you happen to be in the spaceship below under the same conditions, the 2 hour and 50 minute guess may be accurate---depending partially on the length of the trip.
