Plane A is traveling 312 miles per hour and is 450 miles ahead of plane B. Plane B is traveling at 385 miles per hour. How long will it take plane B to catch up to plane A?
\n" ); document.write( "-------
\n" ); document.write( "Plane B DATA:
\n" ); document.write( "rate = 385 mph ; distance = x+450 miles ; time = d/r = (x+450)/385
\n" ); document.write( "----------
\n" ); document.write( "Plane A DATA:
\n" ); document.write( "rate = 312 mph ; distance = x miles ; time = d/r = x/312 hrs
\n" ); document.write( "-----
\n" ); document.write( "Equation::
\n" ); document.write( "time = time
\n" ); document.write( "(x+450)/385 = x/312
\n" ); document.write( "---------------
\n" ); document.write( "312x +312*450 = 385x
\n" ); document.write( "73x = 312*450
\n" ); document.write( "x = 1923.29
\n" ); document.write( "Ans: B time = (1923.29+450)/385 = 6.16 hrs = 6hr 9 min 36 seconds
