General formula: distance = rate*time
--------------------------------------------

Driving marathon. Felix drove 800 miles in x hours on Monday.
a) write a rational expression for his average speed.
rate = distance/time = 800/x mph

b)On Tuesday, he drove for six hours at the same average speed. Write a rational expression for his distance on Tuesday.
800/6 = 400/3 mph
