A new food delivery robot on a college campus is doing test runs at a constant speed of 4 miles per hour. The average test run is 3 miles from the campus cafeteria but varles a distance of 1.5 miles more or less than that.

If x is the number of hours the robot is performing a test run, the equation that can be used to find the minimum and maximum time (in

hours) for a test run is

A. | 3x - 4 | = 1.5

B. | 4x - 3 | = 1.5

C. | 4x - 1.5 | = 3

D. | 3x - 1.5 | = 4

For each test run, the minimum time is

A. 0.375

B. 0.625

C. 0.75

D. 0.83

and the maximum time is

A. 2.125

B. 1.125

C. 1.875
