Seth traveled 1 mile in 57.1 seconds. About how fast does Seth travel in miles per hour?

Answer 1

In order to find miles per hour we must first change the time given to us (57.1 seconds) into hours. We will do this by first changing the seconds to minutes:

57.1 seconds / 60 = .952 minutes

Now we can change our minutes to hours:

.952 minutes / 60= .016 hours

Now to find miles per hour we divide the miles by our time:

1 mile / .016 hours = 63.04 mph

*Note: although I rounded on my time calculations, it's important to try not to round until the very end of a problem.
