Best ResponseYou've already chosen the best response.0Oa>(x15) (x)<Ob 250 With the equation S=So+Vo(t), we can find: Sa = Soa + Voa(t) Sb = Sob + Voa(t) Sa = 0 + (x15)(t) Sb = 250  x(t) Sa = (x15)(t) after 2hr: Sa = (x15)(2) Sb = 250  x(2) Sa = 2x30 Sb = 250  2x When the cars pass each other, it means that Sa = Sb. Therefore, 2x30 = 2502x 4x=280 x=70 Car a: Car b: x15 => 7015 = 55 x = 70 is traveling at 55mph is traveling at 70mph Is that right?
