sorry there's a mistake it suppose to be just Car B

Car A was going 54km/h It would take 13.5 hours for Car B to catch up to car A. 54 x 1.5 = 81 miles (this is how many miles ahead Car A is) 81 / 6 = 13.5 (miles ahead divided by how many miles it catches up per hour gives you 13.5 hours) I did these real quick while waiting for another answer so don't assume they're right :D
