Dieter makes a journey of 430 km, traveling 160 km by bus and 270 km by car. If the car averages 10km/h faster than the bus and the whole journey takes 5h, what is the speed of the car?
I don't get the question.. can anyone help me?? :)

Use d=rt.
Let r = the bus rate. Then the car's rate is r+10.
Since the total time traveled is 5 hours, we have d/r=5
Solve for r.
