Car A Car B
d=rt d = rt
d = ra * 2.4 d = rb 4
ra = rb+22
distances are the same so set the equations equal
ra * 2.4 =rb *4
substitue in for ra
(rb+22) 2.4 =rb *4
distribute
2.4 rb +52.8 = 4 rb
subtract 2.4 rb from each side
52.8 = 1.6 rb
33 = rb
Car b travels at 33 miles per hour
Car a = 33+22
Car a = 55 miles per hour

Answer:
2 solutions (- 4, 4 ) and (- 1, 1 )
Step-by-step explanation:
The solutions are at the points of intersection of the straight line and the curve.
There are 2 points of intersection , thus 2 solutions
The points of intersection are (- 4, 4 ) and (- 1, 1 ) ← solutions
