Answer:
1.25 hours
Step-by-step explanation:
If you're going 60 miles per hour, that's exactly how much miles you travel in an hour if that is your constant speed you are going the entire time, so it is at least 1 hour and we know it's not 4500 hours and it cant be .8 hours or 135 hours, think of yourself going on a caride would it really take 135 hours ? No so its 1.25. Also multiply 60 by 1.25 and you get 75.
