Answer:

Car B was faster . Speed of Car B was 9/8 times  Speed of Car A

Step-by-step explanation:

Distance traveled by Car A = 60 km

Time taken by Car A = [tex]\frac{5}{6} hour[/tex]

Speed =[tex]\frac{Distance}{Time}[/tex]

Speed = [tex]\frac{60}{\frac{5}{6}}[/tex]

Speed of car A=[tex]60 \times \frac{6}{5}= 72 km /hr[/tex]

Distance traveled by Car B = 54 km

Time taken by Car B = [tex]\frac{2}{3} hour[/tex]

Speed of car B= [tex]\frac{Distance}{Time}[/tex]

Speed = [tex]\frac{54}{\frac{2}{3}}[/tex]

Speed of car A=[tex]54 \times \frac{3}{2}= 81 km /hr[/tex]

[tex]\frac{\text{Speed of car B}}{\text{Speed of car A}}=\frac{81}{72}\\\text{Speed of car B}=\frac{81}{72} \times \text{Speed of car A}\\\text{Speed of car B}=\frac{9}{8} \times \text{Speed of car A}[/tex]

So, Car B was faster . Car B was 9/8 times faster than Car A
