The distance a car travel on a certain amount of fuel varies inversely with its speed. If a car traveling 50 mph con travel 300 miles on 10 gallons of fuel, how far could the car travel on10 gallons of fuel at 60 mph?
\n" ); document.write( "-------------
\n" ); document.write( "distance = k*fuel/rate
\n" ); document.write( "---
\n" ); document.write( "Find \"k\" using d=300 when rate = 50 mph and fuel = 10 gals
\n" ); document.write( "300 = k*10/50
\n" ); document.write( "---
\n" ); document.write( "k = 1500
\n" ); document.write( "----
\n" ); document.write( "Equation for this situation:
\n" ); document.write( "d = 1500*f/r
\n" ); document.write( "-------------------------
\n" ); document.write( "How far could the car travel on 10 gallons of fuel at 60 mph?
\n" ); document.write( "-------------
\n" ); document.write( "distance = 1500*10/60 = (1/4)(1000) = 250 miles
\n" ); document.write( "=========================================
