82.) Driving marathon. Felix drove 800 miles in x hours on Monday.
a.) Write a rational expression for his average speed.
Rate * Time=Distance
Rate = Distance/Time
Speed = 800/x
b.) On tuesday he drove for 6 hours at the same average speed. Write a rational expression for his distance on Tuesday.

Rate*Time=Distance
Distance=Rate*Time
Distance = [800/x]
Distance= 4800/8
