Algebra.Com's Answer #584432 by lwsshak3(11628) ![]() You can put this solution on YOUR website! A jet travels 860 km between two cities. It then proceeds to travel at the same speed for an additional 1,030 km in a time that is 0.3 hours longer than the first trip. How much time (in hours) did the second trip require? \n" ); document.write( "*** \n" ); document.write( "let x=travel time of 2nd trip \n" ); document.write( "x-0.3=travel time of 1st trip \n" ); document.write( "speed=distance/travel time (same for both trips) \n" ); document.write( ".. \n" ); document.write( " \n" ); document.write( "1030/x=860/(x-0.3) \n" ); document.write( "860x=1030(x-0.3) \n" ); document.write( "860x=1030x-309 \n" ); document.write( "170x=309 \n" ); document.write( "x≈1.82 \n" ); document.write( "How much time (in hours) did the second trip require? 1.82 \n" ); document.write( " |
