Question

Using the model you chose in the previous problem, estimate the flight time from Memphis to Philadelphia if the distance between the two cities is 874 miles.  Round to the nearest minute.

As a reminder, you chose the model: t = 0.13d + 40 with d representing the distance in miles and t representing the time in minutes.

          hours and           minutes

Answer 1

First, write the equation with all known information:

 

t=0.13d + 40    d=miles and t = minutes    d = 874 miles

 

Substitute in the information you know:

 

t = (0.13 * 874) + 40

 

Calculate - Remember to use the order of operations!

 

t = (113.62) + 40

 

t = 153.62 minutes

 

To round to nearest minute round up from 153.62 to 154
