Two cars drive from town a to town b at constant speeds. the blue car travel 35 miles per hour, and the red car travels 70 miles per hour. the blue car leaves at 10: 30, and the red car leaves at noon. the distance between the two towns is 140 miles. which linear equations represents the red car and the blue car?
a)red car y=70x
blue car y=35x+52.5
b)red car y=35x
blue car y=70x
c)red car y=70x
blue car y=35x
d) red car y=70x+105
blue car y=35x
