Question 898214: An airplane left at 12:00 PM flying towards Chicago at a constant speed of 500 miles per hour. At 3:00 PM the airplane was 2,000 miles from Chicago.
Which equation represents this situation if x is the number of hours after 12:00 PM and y is the number of miles from Chicago?
A. y=2000+500x
B. y=2000 - 500x
C. y=3500-500x
D. y=3500+500x
E. y=1500+500x
I think it's B, because at 3:00 pm it was 2,000 miles and going 500 mph. Is that right?
thanks for the help.

a c and e get further away from Chicago as time increases
when x=1
A) yields 2500
b) yields 1500
c) yields 3000
d) yields 4000
e) yields 2000
when x=5
A) yields 4500
b) yields -500
c) yields 1000
d) yields 6000
e) yields 4000
Which equation yields 2000 when you plug in 3 for x?
A) yields 3500
b) yields 500
c) yields 2000
d) yields 5000
e) yields 3000
