Cecilia makes travel plans for her trip home from Atlantic City to Williamsburg. She plans to make a 2 hour stop in Baltimore. To predict the time of her trip (t) at an average driving speed (s), she uses the equation below: T=2+ 350/s Find the trip times for the average driving speed of 45,55, and 65 miles per hour.

9.778 h

8.364 h

7.385 h

Step-by-step explanation:

In the given expression, "s" is Cecilia's average driving speed in miles per hour, 350 is the distance, in miles, between Atlantic City and Williamsburg, therefore:

For s = 45 mph

For s = 55 mph

For s = 65 mph

to determine the unit cost your would divide the total cost by the number sold.
