if u travel at a rate of 45 miles per hour, how many min will it take you to travel 1 min? justify ur response

Shouldn't your question be "How many minutes does it take to travel one mile"?

There are 60 minutes in an hour so 45 mph =

45 / 60 =.75 miles per minute

If we take the reciprocal we will get minutes per mile:

1 /.75 miles per minute = 1.3333333333 minutes per mile, so it will take 1.33333333 minutes.
