I'm going 80 mph and have 76 miles to go. how much time will it take for me to arrive

You're going at 80 miles per hour.

You have 76 miles left, and you want to find the amount of time it'll take for you to get to your destination.

First, find out the amount of miles per hour you can travel in one minute. Simply divide the number of miles per hour by the number of minutes in an hour.

80 (mph) : 60 (minutes) = 1.333 miles per minute

You have 76 miles to go, and you know you can go 1.333 miles a minute. Simply divide the amount of miles you need to go by the amount of miles you can go per minute to find the total time it takes for you to get to your destination.

76 (miles left) : 1.333 (miles per minute) = 57.014 minutes (round that to 57)

It will take you approximately 57 minutes to get to your destination.
