Which is greater: inches in a mile or seconds in a day? Show how you know.

MrMuchimi

Assuming you don't know the exact numbers, we can sequentially figure out the number of inches in a mile and seconds in a day

Inches in a mile:

There are 5280 feet in a mile.

5280*12 = 63360 inches in a mile

Seconds in a day:

There are 24 hours in a day

There are 24*60 = 1440 minutes in a day

There are 1440*60 = 86400 seconds in a day

There are more seconds in a day than inches in a mile.
