A) x + y = -80
B) 3x = y
x + 3x = -80
4x = -80
x = -20
y = -60
The answer would be d=8t
This would be because the time they want is 1 hour. So when you plug in t as 1 you need d to equal 8. So you just have to change that 6 in the first equation to an 8. This new equation means that the person can travel 8 miles every hour.
