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.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
