Complete Question

Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?

The time it would take at the given speed is  

Explanation:

From the question we are told that

      The time taken to exist the highway is  

      The distance to the exist is  

       Alberta speed is

The time it would take travelling at the given speed is mathematically represented as

  substituting values

Converting to minutes

         1  hour =  60 minutes

So      0.71667 hours = x minutes

   Therefore

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
