Algebra.Com's Answer #583814 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! a hitch hiker begins to walk along a straight road at the rate of 6 mph to the next town, which is 36 miles away. \n" ); document.write( " after 10 minutes a car picks him up and an hour and a quarter after being picked up he is in town. \n" ); document.write( " how far was the car traveling? \n" ); document.write( ": \n" ); document.write( "Let d = the distance the car traveled \n" ); document.write( ": \n" ); document.write( "write a dist equation; dist = time*speed (time in hrs) \n" ); document.write( "hiking dist + car dist = 36 miles \n" ); document.write( " \n" ); document.write( "1 + d = 36 \n" ); document.write( "d = 36 - 1 \n" ); document.write( "d = 35 miles traveled by car \n" ); document.write( ": \n" ); document.write( "You said something about 25 mph, find the speed of the car \n" ); document.write( "35/1.25 = 28 mph is the speed of the car \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Confirm our solution by finding the distance each traveled \n" ); document.write( "10/60 * 6 = 1 mi \n" ); document.write( "1.25 * 28 = 35 mi \n" ); document.write( "----------------- \n" ); document.write( "total dist: 36 mi \n" ); document.write( " \n" ); document.write( " |
