Consider the method get Hours, which is intended to calculate the number of hours that a vehicle takes to travel between two mile markers on a highway if the vehicle travels at a constant speed of 60 miles per hour. A mile marker is a sign showing the number of miles along a road between some fixed location (for example, the beginning of a highway) and the current location.
The following table shows two examples of the intended behavior of getHours, based on the int parameters marker1 and marker2.
marker1 marker2 Return Value
100 220 2.0
100 70 0.5
Consider the following implementation of getHours.
public static double getHours (int marker1, marker2)
{
/* missing statement */
return hours;
}
1. Which of the following statements can replace /* missing statement */ so getHours works as intended?
(A) double hours = (Math. abs (marker1) - Math. abs (marker2)) / 60.0;
(B) double hours = Math. abs (marker1 - marker2 / 60.0)
(C) double hours = Math. abs (marker1 - marker2) / 60.
(D) double hours = Math. abs((marker1 - marker2) / 60);
(E) double hours = (double) (Math. abs (marker1 - marker2) / 60);
