Algebra.Com's Answer #38970 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! Boat is traveling from A to B at 33mph \n" ); document.write( "Plane is also traveling from same A to B at 605mph. \n" ); document.write( "Plane takes 104 hours LESS to make the trip. \n" ); document.write( "How far apart are A and B. \n" ); document.write( ": \n" ); document.write( "It does say they both went from A to B, therefore they are traveling the same distance. If we find the times required to make the trips, it's an easy calculation to find the distance \n" ); document.write( ": \n" ); document.write( "Let t = boat's time to make the trip \n" ); document.write( ": \n" ); document.write( "Then (t-104) = plane's time to make the trip \n" ); document.write( ": \n" ); document.write( "Boat's speed is given as 33 mph; \n" ); document.write( ": \n" ); document.write( "Plane's speed = 605 mph \n" ); document.write( ": \n" ); document.write( "Dist = speed * time \n" ); document.write( ": \n" ); document.write( "Plane's dist = Boat's dist \n" ); document.write( "605(t-104) = 33t \n" ); document.write( "605t - 62920 = 33t \n" ); document.write( "605t - 33t = +62920 \n" ); document.write( "572t = 62920 \n" ); document.write( " t = 62920/572 \n" ); document.write( " t = 110 hrs for the boat to make the trip \n" ); document.write( ": \n" ); document.write( "Remember that Dist = speed * time: \n" ); document.write( ": \n" ); document.write( "Dist = 33 * 110 = 3630 mi \n" ); document.write( ": \n" ); document.write( "We can check out solution by finding the dist the plane travels, it should be the same. \n" ); document.write( "605 *(110-104) = \n" ); document.write( "605 * 6 = 3630 mi also from a to b \n" ); document.write( ": \n" ); document.write( "How's that, did it make sense to you? \n" ); document.write( " |
