Question

PLEASE HELP! I DONT UNDERSTAND! 50 POINTS! A FedEx freight truck carries three tons of packages 660 miles on 90 gallons of diesel fuel from Miami, FL to Atlanta, GA. FedEx makes a graph to represent the miles per gallon the truck uses.

Sketch a graph (Use axis for miles, and another axis for gallons) Label intercepts
what is your domain? explain
what does the origin of this graph represent in this situation? explain

PLEASE ANSWER AND EXPLAIN! I DONT UNDERSTAND THIS

Answer 1

660 / 90 = 7

90 / 660 = 0.13

7 / 13 = 53

13 / 7 = 1

53 / 1 = 53

Answer 53

Answer 2

Graph should represent "miles per gallon" that means the y axis are miles driven with x axis gallons used.

See image attached.

The fuel usage is approximately linear so the graph is a line. The origin of the graph (0,0) corresponds to the starting point in MIami, FL, where 0 gallon have been spent and 0 miles driven. the endpoint corresponds to Atlanta, GA, where 90 gallons have been spent and 660 miles driven. The domain is real numbers in the interval [0,90]. The x intercept is 0, the y intercept is also 0. The range is real numbers in the interval [0,660].
