Mr. and mrs. miller both get in their cars and begin to drive at the same time. mr. miller is 280 mi from their house and drives directly home at a constant rate of 40 mph. mrs. miller is at their house and drives away from the house at a constant rate of 30 mph.
let d represent distance from home, and let t represent time in hours.
which system models this situation?
a. d = 280 + 40t
d = 30t
b. d = 280 − 30t
d = 40t
c. d = 280 − 40t
d = 30t
d. d = 280 − 40t
d = 280 + 30t
