Destination 6420

On the 182 km route, car A left at 9:00 a.m., car B at 9:30 a.m., and car C at 9:45 a.m. All three cars reached their destination at the same time. The average speeds of cars A and B differed by 6.5 km/h. How much did the average rates of cars A and C differ?

Correct answer:

x =  10.5 km/h

Step-by-step explanation:

b = 6.5+a c = a + x  182 = a (t9.00) 182 = b (t9.50) 182 = c (t9.75)  t=13 h x=10.5 km/h  a=182/(t9.00)=182/(139.00)=291=45.5 km/h b=182/(t9.50)=182/(139.50)=52 km/h c=182/(t9.75)=182/(139.75)=56 km/h
